yeah, no.
if you don't have your private keys, you don't own your cryptos. this is a lesson that not everyone has learned. one would think that in the, long ago wake of the Mt. Gox fiasco, that it would be a no brainer to only have what you are comfortable losing on an exchange or a futures market.
it somewhat blows my mind that people play a futures market with cryptos, i understand the whys but... i don't. one of the basic tenets of cryptos is removing the middleman and fractionalized gaming. there is no possible way that these exchanges hold all the BTC that they are said to. there is a finite amount so we know for a fact they can't.
a recent movement called, "Proof of Keys", urges all hodlers to remove their holdings on January 3rd of each year to hold these exchange/markets accountable for their custodianship. as evidenced by this past January, where not many did it, it hasn't quite taken hold. i don't know if it ever will but it is a good idea. without it and allowing these ***** to manipulate crypto, it is just the same old, same old. however, the mechanisms are there so it could be done at any point. a crisis of confidence would be all that would be required to spark it. however, if it comes to a confidence crisis to expose the fractionalization of it all to expose it, those who are long are going to get screwed.
