Stuff like this is why crypto is still not widely accepted yet. Rightly, or wrongly, cryptocurrencies security, reliability and growth hangs on the reputation of exchanges, wallets, and companies in this space that continue to show how early days we are.
One day, user-interfaces on wallets, will be easy for my mom to use, and one day exchanges will have blockchain backed security, which will ultimately prove reliable and secure, but for now, we stumble before we walk.
All these exchanges are trading everything that has something to do with blockchain but they are not on blockchain.
Understood, but many people do not get that. Therefore a black-eye to these exchanges is a black-eye to crypto.
And what I mean about the future being better is that one day crypto exchanges will be mainly decentralized, on the blockchain, and that will be a good day. Decentralized exchanges will be safer, more reliable and that day is not too far off. Yes decentralized exchanges exist today but no amazing ones, they either lack volume, or they cost ethereum to transact, which is a fee we would all love to avoid.
Soon, there will be a better asnwer, and cryptocurrency will be better off for it. And when that happens blockchain tech will be more readily embraced: That is what I meant.
