Today I bought some mining power of the cloud mining platform Hashflare. I paid using Payeer because it's easier to convert STEEM to than Bitcoin as posted in my main account.
Hashflare offers yearly contracts to earn BTC, ETH and ZEC. If the price stays the same you'd get your investment back in around 150-180 days, so you'd get around the double amount you pay in a year. (Here's my Referral Link if you want to sign-up under me.)
I heard that cloud mining isn't good investment. But decided to try anyway and after a year of using Hashflare I say it's not a bad experience and better than leaving the money unused, but if you want to/can invest them yourself then cloud mining might not be suitable for you.
