The reality is that they would not have been able to hold for so long even if they bought 10 years ago. Very few have the patience to wait till 100x or more. Most of the investors will be sold at the idea of 2x or 3x itself. Some of the people that were able to hold for so long were those who had invested and then completely forgot about it. There is one more category of people who had complete trust on BTC and thus they stick with it for years.
it is a great fortune if someone who bought bitcoin 10 years ago then forgot about it and thought back 10 years later and then sold it, but i think the lucky person is only 1%. it's not an easy matter to be able to hold back when they see the bitcoin they buy go up 2x or 10x, only those who really believe in bitcoin who definitely buy it ten years ago, store it and hold it until now.
