There is only about 72k coins available right now and dev holds somewhere 62k coins (LOL!!) not including 50% of STAKING he has been getting....so there is only 5k or 7k from miners. And there was over 50k coins dumped since this morning alone.. not mentioning last couple of days of continuous dumping. SMH lol
Yep, this baby is dead, moving on

I have a different theory.
I think, that ypool was hacked, the wallet stolen and the coins dumped in the market. The dev transferred half of his coins to the exchanges to sell and buy with a bot to create market volume. Then you dumped your 3700 instamined coins to make 1 BTC profit. Holyblood and the other guy that mined with 90THs on ypool also sold some. It is difficult to confirm anything without a good block explorer.
or
the dev dumped his coins
