The age of these coins is not the problem, people don't read the data on the blockchain. There are a lot of very old coins that have never been moved. This is mostly about the amount. It is a very big amount, and if it was a real holder and not some weird hack or something then I am happy for them. This is what it means to believe in Bitcoin, this is what it means to understand Bitcoin. No excuses and selling for emergencies that could have been covered with other money instead. Hold to win!
or it could be a BTC developer. There is a team of developers that maintain this software. Don't tell me they are saints

They are mostly saints and are pretty BTC poor. Don't confuse
them with altcoin scammers
withthat get team allocation, they print coins and tokens for free. This can't happen in Bitcoin.
