Cryptopia fell apart. But before it did, it was an easy to use exchange with fairly high volume.
Who is replacing it now?
Well, I dint think anyone will miss them that much and they were never even among the top 10 exchanges for ones to be looking for replacement for them, they are gone and that is it, we will continue will the existing ones, but right from onset, Binance has been the most popular exchange in the market and I doubt if majority of Binance users even know about cryptopia.
I never knew about them too until I saw the FUD news about them, being hacked on this exchange, and for them to die that way, it shows they were never strong. What would they have done if they were Binance that they stole over 7000BTC from.
Binance has its own fund SAFU to fully cover the losses associated with this incident. If the Cryptopia exchange had a similar fund, they could easily survive this hacking
