Also, I'm not sure if the addresses generated on coinb.in are bech32m
It seems coin.in does not support
taproot and
bech32m.
The last version of coinb.in is 1.7 which was released on
July 2020 while bech32m was first introduced in the
bip-350 on
December 2020.
In any case, when using tools like coinb.in, make sue to download them and run them on an offline device.
So my question is: how do I make a bech32m address and how do I move coins on it? I've been Duck Duck Go-ing my eyes out and can't find any answer on the matter at all... search machines are ruined. Christ, it's so annoying.
You don’t have to buy a hardware wallet to do this. There a good software wallets that support taproot that you can download and use for free. Check the last link in the above reply by tranthidung.
