There are alot of altcoins, on which, there is no effect of the bear market, no matter how down the market came, this token keeps it's price stable, I'm not promoting or sponsoring it, I'm just answering to your question,
Token name is DIFX, it is only listed on its own exchange that's why it does not go down.
Conclusion: the alt with it's own exchange doesn't depend on market, so it could also go up too.
