If you are ok with KYC verification and if you are looking for more Crypto supported I suggest you try Binance

https://www.binance.com/en/buy-BitcoinIs there not a good and legitimate exchange in USA that one can buy bitcoin with their debit or credit card without passing through rigorous KYC. I am asking for someone and not me. Thanks
There are no exchanges yet that don't ask for KYC or without KYC they are all gone and now turn to ask a KYC unlike before.
I heard someone that this one "Localcryptos" doesn't have KYC but I don't how safe it is. And another option to buy in the US with debit/credit card without KYC is to buy directly on Bitcoin ATMs which is already mentioned above.
You can find the map of Bitcoin ATMs from here
