I think i will invest 0.1BTC and then 0.5BTC followed around this week or next week.This shows i really want to trusted you guys...if you are really established/trusted i think you could implement registration/login + reinvest + wallet function.You could actually make HashOcean registration/login function as a model for your development as when i make payment for power using external wallet in that website it show 6 confirmation of payment in real time.It will boost the confident of investor as they could see their money going through 6 confirmation. It just piece of my mind.TQ for reading my post.
