They are great in that area. Took a while make it available, but they wanted to run their own wallet and node instead of entrusting it to a third party before they started offering monero payment.
Secure Secure Messages I’ve seen for people who added in their Matrix contact, which does seem a smart route to go if someone wishes to be contacted over relying on lemmy.
The remote instance admins not having access to IPs is pretty amazing feature. Sort of like a proxy? Makes me glad I chose monero.town over all the random instances out there.
Reason people recommend monero is because crypto like bitcoin has a public ledger, so if you send your bitcoin to a usernet service then the usenet service and along with the exchange used to get the bitcoin will know what you spent the bitcoin on. So you end up having to use mixers to try and hide the transaction.
Monero is just easier where the wallet receiving the Monero should theoretically not know what address it came from because the ledger is private. So once you sent your monero into your own wallet the exchange and anyone you send the monero too would not know the address of your wallet or balance. At least in theory.
You are welcomed to visit !monero@monero.town if you’d like more help. I don’t know much myself, but there’s others there who do.
