But we can change our future. Right now.

Fantasizing about the past is harmful because it creates a sense of lost profit, while it is more productive to focus on the future, which can be influenced now. The past is already unchanged.

Bitcoin gives the opportunity to influence your future. If you don't take advantage of this now, that years later you will fantasize about a time machine in order to move from the future to the present day. I think it's better to try to achieve what you want than to regret later that you didn't take advantage of the opportunity. I have a similar experience with btc when I didn't buy it for half a thousand dollars.

The final decision whether to buy or not to buy bitcoin must be approached with all seriousness so as not to be the loser due to the wrong behavior strategy.
