Hello steemians. We have new cloud mining kid in the town. Sierrahash. They are supposed to be UKbased company with datacentre in the Iceland. They only just started 16 days ago so should be by default highly untrusted, but they are offering 150GH/s Bitcoin mining for registration, so for people who want to have a go and give it try its nice option.
I have bough some hashpower from them and they seem to be about 30% more expensive that their competition Genesis Mining and HashFlare, but they are only ones offering lifetime contract at the moment (well supposing they will last your lifetime;)
You can't really expect any great return of this free offer, but I think its very good way to get people interested in Bitcoin in general, get them make wallet and such. Share with your friends and let more people join the Bitcoin revolution!
I would not recommend anyone to invest more money that you are able to loose, but its worth giving it a go and claim your free hashpower and see how it goes. Please use my referral link if you want to register.

I will do the testing for 1 week and let you guys know if they are paying as supposed and if withdrawals are without any issues.
