This is great news for the blockchain industry.  Obviously Samsung is a huge company and hopefully more companies will join the party.  I think if you are a big company and not at least have a reasearch team looking into on the blockchain technology, you will be looked at as not forward thinking. 

From what I understand, sata cables cannot provide enough power to support multiple risers.  You can use 1 sata cable per 1 riser.  But I chose to use either 6 pin pcie or molex connectors for my risers.  Those connectors support higher power usage. 

Your wallet will depend on what coins you want to hold and how you want to access your funds.  There is no one perfect wallet for all your coins.  For ease of access anywhere on any device, I use online Coinbase.  For desktop wallet where I can keep my own private keys, I use Electrum for btc, Electrum-ltc for litecoin, and MEW for Ethereum.  These serve my needs for now.

It looks like Bitcoin has a nice support at $6500-7000.  Hopefully it takes off again this year.  Negative news and FUD have driven many people away from Bitcoin.  We just need positive news to bring the attention back.  Then it might shoot up to the moon. 

Your wallet will depend on what coin you want to hold.  For me, Bitcoin I use Electrum, litecoin I use electrum-ltc, Ethereum I use MEW, online wallet I use Coinbase/gdax because ease of use and they are fdic insured. 

Right now Bitcoin is certainly the undisputed leader.  But the crypto market is still very much in the early stages of widespread acceptance.  So I do think eventually there maybe a few more cryptos that will rival Bitcoin at the top.  It’s pretty hard to start at the top and stay there indefinitely.  Therefore I choose to also invest in other coins as well to spread the risk and hopefully reap the rewards. 

I think paper wallet is the old school method that people use to take their coins offline.  Although many people still use that method, most people are moving towards hardware wallets for cold storage. 

I’m curious why it is so expensive and difficult to change username.  Is it for security reasons? 

Online wallets are basically any wallets that you can access anywhere from any machine.  They are convenient if you want fast access to your funds.  But that convenience comes with the risk of the wallet getting hacked.  It’s happened to many people before.  Hardware wallets like Nano Ledger or Trezor are offline wallets.  They are less proned to hacking but obviously not as convenient since you need to have the hardware device to get to your funds.  There is really no perfect wallet.  There are advantages and disadvantages to all of them. 

It looks like the crypto market is in a free fall.  Btc around 7k, eth under $400, ltc around $100, alt coins are generally down significantly.  So what is everyone doing?  Go all in and buy more?  Sell and get out while you can?  Hodl and trust the process? 

With gpu prices high and mining profits low, it doesn’t make sense to get into mining at the moment.  I’m one of the ones that just got into gpu mining this year and have been severely disappointed in the returns.  My comfort is that I gained valuable experience in more things crypto.  Lol.

I’m not really sure if mining is worth it at the moment since the crypto market is significantly down.  It’s almost better if you just buy the coins at market prices.  If you buy equipment now to mine, it might take you a couple years to get the return on your investment.  That’s at market prices and if it doesn’t drop even more. 

I’m one of the ones that just got into mining recently this year and it’s defintely hard times.  Not the returns I was expecting at all.  Hopefully things turn around or else it will be a long time before I can recoup my investment. 

Of course nowadays we all shop online to some extent.  Sometimes it’s a much more convenient way to shop.  Certain items are harder to find locally so you might have to go to Amazon or EBay to get them.  Example is it’s almost impossible to find vintage or collectible items unless you expand your search globally. 

I think we are on the way to a cashless society.  It’s a more convenient way to transact.  The fiat curriencies that we know today will be pegged to their individual coins.  The traditional fiat currencies will still exist in that sense but the actual method of exchange will be done electronically.  It will be many many many years down the road for the transition to happen. 

I use Electrum for desktop btc wallet, Electrum-ltc for litecoin wallet, Myetherwallet for Etc, and Coinbase/gdax for exchange wallet.  I’m looking at either Trezor or Nano Ledger for hardware wallet down the road. 

I would connect the Gpu directly to the pcie 16 slot and cable a known good 8-pin power connector to eliminate the risers as the problem.  Maybe you have a bad gpu. 

I believe recent price drops have been due to an influx of bad news.  Facebook and Google have banned ads relating to crypto and ICOs.  Many countries are debating how to regulate the crypto market.  I think the price will rise again once the storm is over.
