Lots of people knew about bitcoin at the early stage, but they never believed in it, they were thinking bitcoin would die, they never expected such an incredible performance from bitcoin, so they never invested in it, but they now regret why they didn’t invest in it at their early stage. Some people refuse to invest in bitcoin currently, just because they think the bitcoin price is too high, and they believe if they invest, they won’t be able to make much profit. I'm sure people like that will be surprised in the near future, and they're going to regret why they didn’t invest now.
The lay people about Bitcoin will regret when they see the development of bitcoin which is much more advanced than other assets. Also their biggest regret is not wanting to learn about bitcoin so it will make them lag behind the times.
Some of the advantages of Bitcoin that we do not realize continue to advance in several countries such as El Salvador and many other countries.
Large banks in many countries have invested in bitcoin and also large companies continue to buy bitcoin in order to change the company's treasury balance sheet to Bitcoin. Of course Bitcoin is very appropriate and quite appropriate to own and also hold in the long term. I think those who sell are those who are weak-handed and do not have broader knowledge about bitcoin. If those who have learned about bitcoin then they continue to buy and hold their Btc holdings.
