Ask that person on how sure he is that platform is good? It's not even listed on CMC so this is not good for that means. And for calling them good that platform should be listed if not the top but atleast on decent position with good volume. So better beware on that and if I were you I stick on binancd or other top exchange since we know they are more secured and provides good trading experience to us.
The main account I have is on the Binance. I agree that Binance is probably the most reliable platform, which is why I keep most of my funds there. I use Fybit for short-term trades with a small trading volume, since my main earnings come from medium-term trades. I also manage a large account on Huobi, from which I receive my percentage for trading operations. Until I trade for a long time on fybit, I won't be able to recommend it to anyone. Therefore, as I wrote earlier, time will tell.
