I have heard of stormgain when they were running some kind of campaign (something like a mining stuffs) and that was the only reason I downloaded it, I never for once made any deposits into it.

Rather than looking for top exchanges I think you should also look for a good non-custodial wallets for your coins, if you’re planning on storing for a long time then consider putting it in a wallet but if it’s for daily trades then exchanges would work better and I don’t think there’s any need mentioning the names of exchanges since previous posts already contains some decent ones.
