Exchange must follow some rules, then they need to take care about this information
That is BS someone trying to buy less than $50 should be able to instantly buy with credit card without any identification, when I was new in crypto I was forced to turn to cloud mining services to obtain some bitcoins because that was the only way until I found some local exchanges selling me and buying from me though under my country's laws, meaning they can never scam me. you just need to find a local exchange that's all.
For some people this is the hard part to buy Bitcoins, because they don't want to give their informations or they don't have the specific necessary informations like documents or bank account to have a credit card for an example. But there isn't nothing to do about it, or you earn all your Bitcoin on the internet working or you need to follow the country regulamentations to have access to Bitcoins.
