Why will btc dropped come on buddy we are not in 2015 or 2016 where hacking of bitfinex causes the price to fall by more than 40%. The amount lost is nothing even if they do sell it price might increase because of the bullish market.

Unfortunately the funds lost can't be returned only time will tell will nicehash compensate the loss.

Honestly it isn't if you observe nicehash simply allowed miners to share their power at the rate they want and interested users payed the appropriate price. Nicehash simply acted like a middleman.
