These Crypto (Brokers?) are all a Ponzi scheme. Or what I refer to as "lifestyle companies". Their lifestyle - not yours.
So. They charge you a commission to buy in, and a commission to sell out. They also take their large salaries out of the pool. Therefore they rely on new people buying in, to pay-out any leaving. That works, until there is a slump. If new chumps stop buying in, there logically is insufficient funds to pay out those wanting to cash in their holdings. All the dealers/brokers hope, is that the price of the crypto will fall sufficiently for them to have the funds to pay them out. If not. Stuff them. Declare bankruptcy.
