I want to buy few bitcoins totally anonymously. Just for experiment

If you would use crypto ATM you have to keep in mind that this is usually the most expensive way to buy Bitcoin, as the fees are mostly 5%, but often more than twice as high. Also, not all crypto ATMs are anonymous, some only require a mobile phone number, while others require scanning a document or even video verification.
I will search for another way...
You can try to find an honest trader in the
Currency exchange board, although I suspect that there is someone who would be willing to sell you a few BTC. For such an amount, I would be extremely careful, because it is quite a lot of money.
