guys i think this guy will scam you.İf you ask how before this site there was btc-stack.com he changed just site's name and maked delays,prices higher.He is propably waiting for enough investment.after it site will go down and will never come back.also you can should at trust profile of the owner.
maybe, definitely eventually but BTCSTACK still up and running fine and an advert on STACK for STACKx2
So in this instance, he has not folded one and made another as old one still working.
The only thing I dont like is. The amount I would make on Newbie level here (0.06BTC) is MINUS 0.01BTC what I would lose (0.07BTC) if I withdraw my money from my level 2 normal BTCSTACK account(I lose level worth 0.07BTC if I withdraw! Now tell me how that adds up!
EDIT: all negative trust was given to owner at start when they all shouted scam at him. At present he has outlasted nearly every other single ponzi released at same time by weeks. I believe those ratings were unfair. To my knowledge has never scammed anyone and even has replenished a level for me when I did by accident. I gave him a positive rating for that.
