I think the reason why people investing in Bitcoin is to earn profit where some are afraid that they will miss the chance to earn profit. You can say that it is very much like FUD or FOMO that they also want to invest. If they really want to invest then they should have bought Bitcoin when it didn't reach the price of bitcoin today.
Are there any other reasons to buy Bitcoin? Of course, that is the main reason and nothing else. That's why, of course, others are digging deeper because bitcoin also has a use case in the life of anyone who believes in holding it to the truth.
And that is that it can be used as a payment, can be used for future savings where the amount you bought can increase even more in a few years that will pass something like that. That's why many people are interested in buying it, and then no one has yet to steal because of this decentralization, and we ourselves hold our Bitcoin.
While everyone invest for profits or let’s say future financial freedom, I myself also invest for future retirement as well.
