Cryptopia was a very small exchange, most of altcoins, that was listed on it, more likely will die. I think soon many low cap altcoins will migrate on Binance chain and their DEX.
I disagree with your opinion.. Probably u are New to Crypto... Cryptopia is no small exchange.. In the good old days Listing on crypto was enough to warrant a old pump.. It's sad the way they went down and it simply shows that any exchange that fails to pay attention to security in this era will become easy food for hackers..
