Invest - 10.0 BTC
Increase to - 30.0 BTC in one month
-->> this look quite spammy ..if this has case then all people in work will be millionaire in a year ..and doubling or tripling you bitcoin is quite difficultly other then you get jackpot in gambling
I understand how it sounds; that's why you're beginning with 0.1
BTC, in one month make 0.3
BTC, pocket the 0.1 you invested and invest in the remaining 0.2 the following month. When you earn 0.6, pocket 0.1 and reinvest in the 0.5. For the 0.5 investment you'll earn 1.5, pocket 0.5 and invest in 1 etc
It will take a number of months to hit there. As long as cryptocurrency will survive.
Okk but where this will work in which platform or what is basic idea or way ..if you don't tell its quite difficult for any one to believe ..as you are quite new to this forum adn asking for .01 so i thing no one can provide you like this its better if you do escow the fund and then tell if that work then no problem of payment if this another scam like what happening right now in market it will be problem for you
