New to investing and cryptos here.

I have some dimecoin on YObit exchange... but I can't do anything with it.

I try to exchange for another crypto and my order just waits for like 5 days with nothing happening.
I've tried sending it cryptopia but the dime wallet has been under maintenance for like a week at least
Despite dimecoin price changing constantly, my 'est btc' balance stays exactly the same. How often does this exchange update prices?

I feel like I made a mistake putting my money into YObit
