In the early days of Bitcoin, it may have been just luck for some who bought and forgot about Bitcoin in their wallets for a long time and then woke up to a crazy price rise, but after that it was no longer just luck, it was actually a rational choice.
It is not easy for all people to believe in something new and continue steadily on the same path until achieving success, as happened with Saylor or Bukele. Yes, these people have proven their practical belief in Bitcoin despite the severe criticism they were subjected to in the winter of cryptocurrencies.
As for me, I am a bit of a Bitcoin holder, albeit a small amount, and I believe that Bitcoin is a successful investment in the long term, as it is a hedge and a store of value at the same time.
