how can u be sure it will be 1$ in 7days
Go research the coin and learn about the event and business plan then you will know.
lol the marketcap of 4.5 million dollar right now is really insane, but it will never reach 1 dollar = 91 million dollar marketcap
this would mean over 220.000 satoshi, lol you guys are funny here.

Oh so NOW you believe it can reach $10? you just wanted to find one for cheaper and advertise it here so it's less of a risk for you with the same rewards, eh? good try, but I noticed, lol
