I wonder ho much greed you'll be feeling if those who control the mining pools of BTC decide to put all those profits to work in the futures market and short the shit out of it! Only to then, buy it all back when every retail investor pukes and sells into the mother of all down trends.
Perhaps the gratitude you'll feel then is to be grateful you didn't lose you're shirt, just your unrealized gains.
Be careful out there. These are dangerous times for crypto, especially BTC.
