mkei is asked to make a subscription message, but I have no btc address anywhere in my profile and on the forum so that I can confirm it, and the lostup to the account is completely closed, how do I make a signature? or just make a signature with your btc address without confirmation on the forum?
It needs to be from an address posted on the forum. If you sent one via PMs then that could also be used.
Edit: you've posted an eth address here which could be used:
what actions should I take now? can I create a signature with an eth wallet? and where can I do it?
