I don't know why exchanges end up bankrupt since their business only takes trading fees.
Probably the fees can't cover the costs of running the service.
Presumably that would be true for an exchange with a ton of overhead, but like Rikafip and dkbit98 I'd never heard of BitFront before, and they're based in the US where I live. They couldn't be that big, right? **
edit: I just read dkbit's whole post, including their pathetic trading pairs** And it's either that or their trading volume was absurdly low, kind of like that small exchange that used to list Curecoin. I think it was shorelinecrypto or something similar, and they also went out of business a while back.
This has nothing to do with the other bankruptcies in the news, however. And I'd point out that there have been a
lot of fly-by-night exchanges that have come and gone over the years, because of not being profitable or through exit scams. Unless the crypto exchange space consolidates and we're left with a handful of big players, I have no doubt we'll be seeing a lot more come and go.
And how the hell is it that shitty exchanges like Yobit are still in business?
