Coinbase is one of the easiest ways to buy, sell and hold cryptocurrencies, which earns it the first spot on this list. With Coinbase, you can connect to a U.S. bank account and easily transfer dollars in or out of your dollar wallet. You can use those dollars, or transfer in new ones, to buy and sell. In addition to Bitcoin, Coinbase currently supports Bitcoin Cash, Ethereum and Litecoin. There are constant rumors of additional currencies like Ripple getting support from Coinbase as well.
While the big upside of Coinbase is ease of use, that is offset with some worries about security. Mt. Gox was at one point the dominant platform for Bitcoin and other currencies. That is until it was hacked and lost nearly half a billion dollars in user currency. But Coinbase did learn from Mt. Gox’s loss, and has very firm security in place and regularly updates and improves the entire user experience.
Blockchain is the technology that allows Bitcoin and other digital currencies to exist. Expect to hear more about Blockchain far beyond the digital currency world. Blockchain.info is similar to Coinbase in that it is an online wallet, but you can’t buy or sell directly through Blockchain, which means your Bitcoin storage is separate from your Bitcoin marketplace.
Because it isn’t a full exchange, it is considered to be more secure than a site like Coinbase, where you can bet that bad guys are constantly attempting to hack. If you are not a “computer person,” using an exchange like Coinbase is much easier. This separation adds a level of security, but also a level of complexity in your Bitcoin use.
Trezor isn’t a full buying and selling platform like Coinbase. Instead, it is simply a place to store your Bitcoin. Trezor is a physical device that plugs into your computer, tablet or phone to access your coins. The Trezor wallet works with multiple currencies and works as a password manager, two-factor authentication device and other useful features.
This wallet offers some protections against lost passwords and lost devices, but you should learn from other’s sad lessons and make sure that never, ever happens. The entire point of this digital Bitcoin wallet is to keep others from stealing your Bitcoin, so you can assume the recovery process is not necessarily an easy one.
Elon Musk has revealed proposals for one of his most ambitious projects to date – intercontinental rocket flights for passengers that will take under half an hour.
The billionaire entrepreneur said the BFR spacecraft unveiled by his company SpaceX will be able to fly to most places on earth in under 30 minutes and anywhere in under an hour, with the cost roughly equivalent to an economy flight on a passenger jet.
The reusable rockets would apparently have a maximum speed of 27,000 km per hour (16,777 mph), although earth flights would travel at just over 7,000mph, allowing flights of thousands of miles in as little as 22 minutes.
The BFR (which stands for big f****** rocket) is a newly-unveiled spacecraft that Musk says will be able to travel to Mars, and which is due to be launched for the first time in 2022 before colonising the planet from 2024.
However, he said there was no reason why the rockets should not be able to travel to different locations on earth.
“If you build a ship that’s capable of going to Mars, what if you take that same ship and go to another place on earth, so we looked at that and the results are quite interesting,” he said. He later added that “cost per seat should be about the same as full fare economy in an aircraft”.
SpaceX claimed that it would be able to fly from Hong Kong to Singapore in 22 minutes, New York to London in 29 minutes, and Sydney to London in 51 minutes.
An animated video released by SpaceX shows passengers embarking on the rocket by taking boats to floating launchpads. Once in orbit the spacecraft would split from its booster and vertically land on a launchpad in another city. By re-using rockets, Musk plans to dramatically bring down the cost of travel.
Musk says the BFR would be able to replace SpaceX’s existing lineup of rockets, which are currently used for missions such as trips to the International Space Station.
What are the Best Bitcoin ATM Cards 2018 Comparison of Bitcoin Debit Credit Card Visa Master
Advantage of using an Bitcoin debit card
The pros are pretty obvious – you can now Online/virtually buy anything with Bitcoin. Lot of Places that accepts credit or debit cards would accept your Bitcoin debit card as well “in Future” “Hopefully not the Case yet. The merchant gets paid in his own shop Based currency by the debit company, the charge will be deducted from your Bitcoin balance. This allows you to run purely on Bitcoin, on some Cases.
As an example, if I travel abroad I mostly take my Bitcoin debit-card as backup card in case i get robbed or anything get´s stolen. We call it actually the traveller’s check of digital age 2018.
The Contras of using a Bitcoin debit card
The major con of a Bitcoin debit card is centralization. In order to use the card you have to deposit the money into your account at the debit card company – that means you’re giving control over your coins to a 3rd party´s. Reduce the risk by not deposit too much Bitcoins into your account – basically deposit only an amount you feel free to loose in case of an hack. Using the service of these companies comes with a price – as you will see the friendly fees that Bitcoin debit card companies charge you.
At the moment there are several Bitcoin debit card companies on the Market a lot of Scams btw. so be Careful, do your research, play through all szenarios before , here i am going to show you a short summary of the best ones in my View i will display as well the pros and cons of them.
Previously known as e-coin, the company rebranded to Wirex in 2016. They supplies Chip & Pin visa debit card that can be loaded through your Wirex app (desktop or mobilephone). The fees are pretty same to other cards – costing 3% for international transactions, $2.5 for ATM withdrawal and $17 to get your physical shipped to you wanted destination. The company supplies as well an virtual card if you don’t want the actual plastic. Like Xapo, Wirex also service fees, they charge them on an monthly and not on an annual basis ($1/month).
Pros: Well known Payment Gateway, cards accepted worldwide
cons: Limited to US residents only, doesn’t have chip and pin, requires anverification
Bitpay is an well-known company in the Bitcoin eco-system they provide payment solutions for businesses and individuals. They allow you to get a prepaid Visa card that you can Load through your Bitpay account. The BitPay Prepaid Visa® Card is available for residents in all 50 US states. You should have an home address (no PO boxes allowed), government-issued ID, and Social Security number to apply if you have all that stuff, go for it.
The card costs an flat fee of about $9.95 and takes around 7 days to arrive in your Mailbox. When you Travel outside of the United States you will pay a fee of 3% to cover the currency conversion rate. There is also a $2.00 fee for ATM or cash-back withdrawals inside the US and an $3.00 fee for all ATM or cash-back withdrawals outside of the country. Check out the complete fee list here. There are no transaction fees for the Bitpay card itself.
Pros: Worldwide Available, offers physical and virtual cards
cons: maintenance and loading fees
Cryptopay supplies you an Bitcoin debit card that is worldwide available (unlike Bitpay). You can both order a physical card with a chip & pin, or a virtual debit card if you’re just into online shopping. Another great PRO of Cryptopay is that you do not have to supply full id verification if you don’t need high card limit thats pretty nice.
The physical card cost about $15 and is shipped for free worldwide and fast. ATM withdrawal costs around $2.5 and international currency change adds another 3% on each transaction. I don’t like for example that this card has a monthly maintenance fee of $1 and a 1% commission for loading on money. And If you’re not verified you can load up to €2500 in your card but not more than that.
Pros: Ships to “most” countries, well established company reputation
cons: Redundant fees (IMO), no chip & pin
Xapo was one of the first CC Vendor companies to supply a Bitcoin debit card. Just like Bitpay it offer a “simple” credit card that does not have a chip & pin system (it is possible to get a chip & pin card, I personally did not). The cost of the card is around $20 and it does have an annual fee of $12/year after the first year.
Xapo ships their cards worldwide according to their website. Also their card actually has a “change pin” fee which seems pretty sht. You can use the card without Big verification but you will be limited to $2500.
Pros: Easily connection to your Coinbase account, low fees
cons: Available only in 45 states in the US, Coinbase limited to certain countries as well
Shift position themselves as “the first US Bitcoin debit card”. They supplie a debit card that is connected to your Coinbase.com account. However, even though it’s supposed to be the US debit card it’s available only in 45 out of 50 states at the moment, which is pretty odd.
The card costs a cute $10 to produce and has no ongoing fees. There is of course the standard 3% international transaction fee and $2.5 flat ATM withdrawal fee, which is pretty nice.
What Bitcoin Credit Card should you Looking for?
The Most of these cards are actually the same. They probably use all the same plastic card supplier to run their business as well and the difference is only in their brand Look. Personally I’d advise making sure the card you choose is available in your country and then choose the one with the lowest fees. I’d definitely try to avoid cards with ongoing fees (i.e. Wirex, Xapo). For example, if you live in the US, use Shift that is an reasonable option.
In addition to the cards reviewed in this post there are also ANXPRO and CoinsBank that supply Bitcoin debit card – have a look at them as well, they are listed in the table at the top of this page.
Why FPGA will rule Cryptomining 2018 Evaluate the Chance To Jump Into the FPGA Train Now! – FPGA for Dummies
The Cryptomining market has been crazy this last year. As we talked about before, we came in last year wanting to get involved in mining. I read the articles and gathered the trade tested advice, which said buy an asic. It has more hashing power for the lowest possible power, less power makes more money. It all made sense, so I purchased an ASIC.
After purchasing it, I felt really well. There are still very good machines, but I soon realized that if the market goes down much or if other people buy a ton of ASICS on the algorithm (algo) that your profitability will decrease as the difficulty increases. So what other options do you have? Pretty Frustrating if you invested a lot of cash and Time in your GPU and Asics …
The traditional way of thinking is to go to GPUs if you don’t do ASIC’s and that is a solid plan. GPU’s are very flexible due to their ability to dynamically change to any algo/coin depending on price, difficulty, and GPU’s hashing power in just a few seconds. But it isn’t just GPU or ASIC, recent history has ignored a key player… the FPGA.
So what is an FPGA?
FPGA stands for Field Programmable Gate Array, and it is a device that has a series of gate arrays (obviously) that create truth tables to calculate inputs from a data stream, and output a desired result. In industry you can use this to optimize an industry process, such as cutting 2x4s from a log, provide machine learning or even to perform DNA sequencing.
FPGA’s excel at any task that can be done in a parallel process, such as a mining hash to create an output resulting in a successful hash, and if you’re lucky a successful block.
For more information on FPGA’s specifically check out Intel’s book “FPGA’s for dummies”.
While GPU’s are significantly more powerful than CPU’s, both by power and hashing/watt, because of the FGPA’s inherent parallelism, they can be about 15 times more efficient at making hashes and about 50-100x more efficient by hash/watt output. Check out some research by Tomas, Howes and Luk on the subject. It is a few years old, but still holds true. I have grabbed a snippet from the research, it is a great read.
I apologize for the random number generators (RNG), but I couldn’t find that quick any relevant data on bench testing GPU vs FPGA in real life for mining, due to FPGA is still kind a Secret and the mass run has not started yet, I had to go to the next best thing and creating RNG’s are actually pretty similar to hashing as we are doing brute force hashing similar to using hashcat. Numbers will be different but the scale & magnitude should be similar.
SO what does this all mean? Well you know me, lets do the calculations!
So if the FPGA is so great, then where are they?
FPGA has one Achilles heel when it comes to the programming of it. FPGA runs on a language called HDL (Hardware Descriptive Language) which requires you to program the devices physical hardware such as the gate arrays and static IP manually!
Luckily we have developed a semi automatic language(s) VHDL. Which is a visual way of programming it and you literally draw out a circuit and it literally burns in an image of the circuit your drew. There are not subroutines that run to solve problems and it emulates the technology it actually IS the technology that is used to solve problems.
Verilog came by and allowed programmers to program in higher level code, but is still very hardware language based, this has helped streamline FPGA’s and make them easier to program, but things are even better now, because of OpenCL.
OpenCL (Open Computer Language) is a cross platform high level programming language derived from C. This platform runs the subroutines in your CPU and your GPU and yes even CCminer/Cgminer. This cross platform technology explains how to use the hardware it has based on a separate configuration file, while the base code stays the same. You do need to optimize it, but that is easier than writing all new code.
OK, big deal. It is a huge deal. It means that a programmer who knows C can program the FPGA without a ton of knowledge of Verilog/VHDL or HDL, lowering programming time and allowing more moding faster.
The only issue you are going to run into is that the GPU is more fluid, it can change algo’s at will and quickly, while the FPGA even with OpenCL will need to be optimized and flashed to run each possible algorithm. This is a ton of work, but the gains could be quite great. At this time there is not the capability for dynamic switching. Time will tell when this capability will come though.
