Question

bitcoin

Is it worth investing or everything has already passed.

Answer 1

Everything has gone to the clouds. cex.io.
Gigahashes are bought for bitcoins, bitcoins can be immediately deposited through the metabank. With the current complexity, the payback is about 4 months. Gigahashes can be sold, cue balls can be withdrawn. 4 currencies are mined at once: BTC, NMC, IXC, DVC. Well, it's fun to play around. Well, there is a mini-exchange, you can trade gigahashes. While gigahashes are for sale, but not yet bought, they continue to mine.

Answer 3

You can invest, but the question is how long it will take to recoup the investment. With free electricity, this will be easier. You need to calculate the profit based on the fact that the complexity will increase. If you order new ASICs like CoinCraft or any others at 28nm, you should see what other providers will deliver at the same time and you can estimate how much the network capacity will increase.
If you look to the future and do not hope for a quick profit, this is a normal topic. If you need to get money in the foreseeable future, it is better to buy bitcoins, which will grow on their own.
