Could you tell me what's a copper member please ?
You have been here since 2017, and you don't know what copper membership is?

The rule is there to curb cheating by account farmers. Lots of contest abuses have happened in the past when brand-new accounts were allowed to participate. Going around it means you would have allowed all sorts of cheat to enroll.
I'm pretty slow I know that, I just installed electrum to verify my bitcoin address. Yes I know it's crazy, but that's how it is when you have kids and a (ex)husband who doesn't do anything at home

So maybe the solution would be for Cryptotag to announce the contest on the forum 6 months in advance (on X for example) so that people have time to register and earn merits, right?
