I have also wondered about this actually. It somehow amuses me. I can remember many years ago that the exchanges to be avoided like the plague are the likes of YoBit and HitBTC. Their brands are almost openly equated with scam. But look how they've survived all the things that caused great exchanges and other too-big-to-fail platforms to lay off employees and even file bankruptcies. It's funny how it seems the last laugh is theirs.
Because YoBit is an outright scam. They don't need to worry about bank runs or anything like that, because they are quite happy to just shut down withdrawals and out right steal the coins of their users. Not to mention that the majority of shitcoins you can trade on YoBit don't actually have a blockchain at all and are created by YoBit only to separate idiots from their bitcoin. It doesn't matter if someone wants to withdraw 10 trillion MadeUpYoBitCoinNumber14, since YoBit can just create that out of thin air whenever they need.
The most surprising thing here is how they manage to continue to attract a steady stream of newbies and idiots to keep them running, even during a bear market. Although their outgoings will be very minimal since they don't need to pay any support staff or indeed process any withdrawals.
This, yobit has been listing and promoting self-proclaimed Ponzi schemes and "cryptocurrencies" without a blockchain for like a decade.
Then they start hosting their own ponzis, branding them as "rise only markets", "investbox" and others, at this point just plainly steal the coins will be an improvement. Yet people still fall for it, even when the sheer number of pyramid schemes available
