I am looking for a service to buy a small amount of BTC without invasive procedures.
As far as I remember there were services that didn't require KYC as long as the amount was small but I don't remember their names.
I don't want to undergo verification for such an insignificant amount and I am looking for a fast and easy way.
P2P?
I know that there were some options to buy "Bitcoin Vouchers" with EU (personal) paypal accounts, IDEAL / and perhaps credit cards too. (Although i kind of doubt the latter.)
See if it still works for you:
https://cryptovoucher.io/ , looks like they support an even wider range of options nowadays.
Edit: People have been Pm'ing me if i have used them before: the answer is no. I also read that they might not accept you for various reasons, or ask you for KYC if you use certain payment methods, so please, DYOR before deciding to use them (maybe buy a small amount first with your preferred payment method, and see if that works?).
