it still lives :D17 btc invested = not dead
The weekly invested stats went from ~700 to ~200 to ~60 to now 17 btc. The death of ponzi isn't far away.

...to now ~61. Not so bad, isn't it?
The ponzi got 61 btc last week, not because it was doing great but because it was having double spend problem with 0 fee deposits.
Cheako's post below explains clearly how it has gone to 61 btc.
Firstly the 60BTC figure is a little exaggerated. What happened was that all the payouts where invalidated on the bitcoin network and the software started paying out NEW contributions when the /spent/ funds became available.
So a lot of the 60BTC was ppl hammering the 'now fully funded' Ponzi till the account was empty. This effectively started a new round.
Look at the deposits from 2015-01-31 19:29:06 to 2015-02-02 02:37:24. These are the accounts who were paid out to this week.
