So, any of these have been actually opened? Ever?
All wallet passwords are supposed to be long or very complex to build. As far as I know, only one wallet with more than 30 bitcoins was opened.
Yes this is true statement if you talk about Bitcoin in 2020, in 20k price range. All of the wallets (most of them anyway) are from 2010-sh period when BTC was at $200 , password standards were a bit easier 10 yrs ago as compute power potential was a LOT less than today, so considering all this, I'm really surprised that besides all those fake wallets, non of the real ones were actually cracked.
