Here's my Raspberry Pi rig with it's new LCD and clear case (and I should have another 4 BEs to add coming in the mail today):

I got this from Newegg. I chose it based on price and a 2A power supply. It seems to be working ok so far:

I'm using 4 Block Eruptors. The way the ports are situated on the 7 port hub, you can only put 2 in the front (where there are actually 3 ports) and probably none in the back (where there is 1), but you can put 3 on top. I'm only planning on using the 4, so it works fine for me.

However, I am finding I'm unable to keep Minepeon running for more than 24 hours at a time. I'm not sure where the problem is yet. I'm going to have to hook up a keyboard so I can see what's going on.

Yeah, I wasn't necessarily meaning you should mine with BTCGuild, they just have really good instructions. I actually use abcpool.co for my mining.

I've currently got 2 x 7950 and 4 x USB Block Eruptors, which puts me at about 2.3 GH/s. Which puts me at about where I was at a month ago with just the 2 x 7950s...

Hey, thanks for the tip on MinePeon, by the way. I realized I have a Raspberry Pi sitting in a box doing nothing, so I moved my Block Eruptors over to it. That's definitely the easiest setup I've ever done.

Go to BTCGuild and follow their instructions for BFGMiner. It's much easier.

Pardon the mess, but here's the ugly thing I've put together:

Just be aware that you'll never even come close to breaking even at those prices.

You need to be very careful, now a lot of scams everywhere in the world of cryptocurrencies, check carefully any information

Bitcoin has become less speculative coin, began to appear a lot of infrastructure around it and fine, forward only growth

The best solution for you is to keep your purchased coins for 1-2 years and not sell, then you are more likely to become rich

I do not believe in it and do not recognize it as a cryptocurrency, you rightly said that it is interesting only to banks and no more. As a cryptocurrency it has no prospects

The situation may change if one of the altcoins will be able to overtake bitcoin by capitalization, but this is not expected in the near future

Work on and do not give up, soon you will succeed. You have a very good start, don't stop

Now it is very risky to look for undervalued, the best solution is to invest in the TOP 10-20 coins and wait for them to grow

At the moment, any coins from the TOP 10 will be a good investment, invest in them and with a greater probability you will find yourself with a profit

Learn to control your emotions and blindly believe all the news, many of them manipulating the market to take away your bitcoins

This is one of the most popular wallets for the forum at the moment, the site is completely safe if you are careful and do not get caught by scammers

The most important thing is that no Bank in which case will not block your account and instant transfers without a fee anywhere in the world, it's amazing

Ethereum has a lot of problems at the moment and it affected the price, if everything is fixed in the near future, it will be all right

Your hopes can be justified, the main thing is to choose the right coins that will remain alive after such a period of time
