I don't think any of the big investors in cryptos (the whales; mostly companies and super rich individuals) invest more money than they can afford to lose and certainly don't need to withdraw their investment to pay their day-to-day expenses. Everything began on things by Segwit in bitcoin and ended bitcoin ATH 20k. That was year of big promotion from mass media. 2018 year it's year when big investors will go to market with legal rights.
