^^ That link above do really help and I do really tend to post the same link but since it was given already then I would rather put some advice since your 19 years old still better to keep away on these kind of sites which do offer GH supposed into these cloud mining sites which are totally Ponzi scheme scam sites which would eventually ran off later on and wont pay you up.If you do try to see on similar sites into these days for sure you will still find some on this kind which should really be avoided if you don't really like to be scam and lost up your precious bitcoin.
