My worst mistake in bitcoin is I created a bitcoin talk account in 2017 and neglecting it and now the merit system came up and its really hard to rank up. That is my worst mistake and biggest regret in bitcoin.
what about yours?
Can't you just log in and use your old Bitcointalk account?
My biggest regret/mistake is not buying Bitcoin and other crypto sooner.
