He is new in crypto, you can understand that OP must have heard the news of those binance hacks, strange he hasn't heard that binance got it all covered. He also don't know about changelly scam accusations, no research must have been done by him to learn which brokers to go with but to let you know BInance is very reputable to bitcointalk users. Binance still is one of the best so far that I have used the fact that a user can withdraw few bits of BTC unlike some exchanges.
Why scammy? Binance is one of the most top tier exchange as of this moment.I don't know how much fees different between binance and changelly but somehow
its understandable because Changelly is an instant exchange site rather than an entire platform.If you do need to select then both sites is legit.
It might be due to the bad news (leaks, hacks) that went around few weeks ago but that shouldn't stop us from using them in the end they're still an exchange we should always move our funds after trading.
I know some people that use HitBTC as well, but I'm pretty sure they do request KYC if that's something you're looking for.
KYC is optional on HitBTC, limits are smaller than Binance they have a 5 BTC monthly limit for accounts that aren't verified.
