in the first place, you have to be aware that every single "investment" sites are all scams, due to the fact that payouts depend on the amount of money coming in from the new people investing as well. you also have to understand that these schemes are called "ponzis" which 1) doesn't sound good (i mean by the name "ponzi" it sounds like... well, yeah) and 2) if they say they can double your money because they mine coins and they do trading, then why not just put your money in bitcoin-altcoin trading and see your bitcoin grow in a couple of days, even months.
stop giving in to these sites and start earning your own way instead
I thought thats all ponzis operate lol.
New deposits are feeding old investors while marketing new depositers.. its a never ending cycle until
there is no more deposits left to pay people lol.
Quoting the bold syntax ; Scammers now a-days no longer payout unitl they have none to pay, they run away when their pot is filled hence why a lot of sites stop paying after a couple of weeks or even days. They are all a scam to begin with.
