I do not think that these methods are ideal for this year since many things have happened recently, for example:
- Localbitcoin has placed restrictions on many countries, so I do not think it is the right place for many citizens, especially since such restrictions may be imposed on more countries.
- The same applies to Paxful.
- Bitcoin ATMs: These machines are not available all over the world, so it is your location that determines the benefit in addition to the high fees.
- Bisq: There are not enough trading volumes.
LocalBitcoins/Paxful are both pretty good if you're in the US, though you are right about the fact of increased KYC regulations in the last few years. Sucks, but that's the way it goes.
Bitcoin ATM's are pretty solid if you're in the US (and some other countries) though you're paying a pretty penny to buy Bitcoin without using any sort of KYC stuff. It's typically a few percent (up to 10-15 percent)
Bisq kinda sucks cause of the volume problem, plus there are a good deal of restrictions present on volume from new users. I love the idea behind it, but it doesn't work if there's no volume (or little volume)
