Ponzi.s seem not to be present as much as they use to
ED seem to have stole tens of bitcoins so any new Bitcoin website is a threat
from ponzi and hyips there are only few people that makes money.Rest of people lose money due to their greediness and Dreams to get rich quick
Those ponzies keep flowing because there are people who keeps depositing money into those sites, if they have so much money, they should trade some alt coins instead of that..
