Gainbitcoin is probably a scam. We wouldn't recommend anyone to invest in this company. We have tried to invest but we don´t receive any payouts. In the customer area, we tried to make a refund and we did provide all information. However, the support kept asking for information until they finally canceled it. After this, we haven't heard anything. Gainbitcoin also promises profits no other legit cloud mining company is close to being able to payout. They are mentioned as a scam company in the Coinjournal.
We hasn't received any payout at all from Gainbitcoin. The site is very slow and hard to navigate. Gainbitcoin support is very hard to get any answers from at all.

Alternative Cryptocurrency investments
Alternative cryptocurrency investments to cloud mining are peer-to-peer, peer-to-business and margin lending. There are some peer-to-peer companies like BTCjam and Loanbase. However, the idea is new and we haven´t experienced stable ROI yet with these companies. We recommend Bitfinex for margin funding and Bitbond for peer-to-business lending. Payouts from Bitfinex margin lending varies but around 10 % yearly ROI is achievable. Bitbond is also quite new company and we recommend to start with small volumes.
