Its not a "problem" persay but I hate having to have accounts on 6 different exchanges to buy the coins I want and having to move coins all the damn time around from exchange to wallet to another exchange back to wallet to exchange.. anyways.. I can't wait for loopring and other decentralized protocols to be released mainstream so I can just trade directly from my wallet using smart contracts.. is just a pain keeping up with the flow of things when its all over the place in different amounts. As far as actual problems go.. I'd say the the biggest problem in crypto right now is shilling and pump and dumps.. the whole mccaffee movement in December may take months to get over considering how much people got rekt and how irresponsible alt coin investments really got. So many alt coins are overvaluated with no working product and all the investors are bag hodling and wanting out at any level of profit.. so the cycle of pump and dumping continues.
Is this not why you got into it in the first place?
I mean, if you want no volatility, go to a stock market
