Yes, all the time. I usually pay a 1 cent fee and the transaction goes through in seconds. Not sure what you're talking about.

I can send you some if you want to try it out, just drop an address(for a wallet I recommend cakewallet, but any popular open source wallet works).

I'm talking about Monero specifically, but your reply makes no sense because there are cryptos that have 0 transaction fee and instant confirmaiton. But they are less secure and private so I don't use them, I only use Monero.

Yeah, monero has low transaction fees. And is a pain in the ass to get, even more so in significant quantity or at a good exchange rate. You pay a significant premium for the privacy. So just different types of fees. Monero is also far from instant in my experience.

I too have plenty of purchasing experience with crypto and I wouldn’t advocate for it for any legal transaction.
