Ok, scam & ponzi things aside.
The only reason somebody puts a timeframe on withdrawals is cause they don't have money to pay. He or She, currently has 150BTC in the account but how much of that needs to be paid out. Monday, Tuesday & Todays and i bet he doesn't have that much. Bottom line he is trading/operating while insolvent which is also criminal and by default proves its a ponzi. You can't take from peter to pay paul.
how many times has the hot wallet been cleaned out over the past months/year? Remember everyone always claims "its the end" when the all the hot wallet BTC gets moved? So that means there's plenty of BTC 'available' to pay out for withdrawals.
Obviously something is going on with Marcello/admin for the drop in rewards, slower payouts. If the site was handing out more BTC than it was pulling in from investors, why wouldnt marcelo pull the plug? Why would he run the site at a loss if it is a ponzi like you all assure us it is (despite the fact that you still have no proof either way).
Ask someone who believes in God, what proof do you have God exists? What proof do you have God doesn't exist?!
as i said before, either stick some fukn coin in there or stfu.
