and "how to buy monero?" u may ask
well, there's Haveno that is built for that as the Monero DEX to onramp/offramp
(it's a fork of Bisq, the original Bitcoin DEX)
the network for it would be "Retoswap":
https://retoswap.com/
github link for it would be:
https://github.com/retoaccess1/haveno-reto/releases/
there was an other network but they didnt update to the newer 1.8.0 haveno version so retoswap is currently the network for it
and while it might seems to be a lot of work to "install an app thing", that is pretty much the best option the whole cryptospace has to offer as a whole so far
Haveno/Retoswap was even namedropped by a popular twatter user with alot of followers, as can be seen from that thread:
https://monero.forum/thread/haveno-network-retoswap-not-affected-current-bisq-1-security-issue-thumbup
installing the app shouldnt be the hard part
the part that most people are apprehending is "setting up the account thing"
but is pretty much just going in the menus, filling up the necessary information for payment options then browsing the active trades and taking or making an offer
the first step is the always the harder step, but once this is setup and a first trade has been completed, all the other trades afterward do go very smoothly as it would be setup for them already
"cash by mail" would be the prefered option, but for the ones having access to bank accounts and so on, this is also supported by the app, alongside other payments methods like paypal, venmo and the likes, cash by mail the best tho
which there's a guide from a trusted cash-by-mail provider going a bit more in-depth regarding that over there:
