When I tried to link my segwit (starts with 3) with the transition bot it replied with this:
"Only P2PKH addresses (those that start with 1) can sign messages."
it said i can verify with a microtransaction but i rather use signing messages and dont see why it wouldnt work.
It doesn't matter what you rather do.
Your option is to do what the bot says or not do it at all.
You can't sign with a SW address, so you can't do it.
That said, if you want to register by using the signing method, then move your coins to an address that can actually sign messages (legacy / addresses starting with a 1).
This isnt helpful at all and with terrible attitude... Regardless of what i do, devs should try and make their bot work well and should i not report a possible bug? There is no reason signing doesnt work with segwit address.
