I agree with what you just said. Regret is just a feeling of sadness and disappointment, but we can channel that pain into building our Bitcoin portfolio. Whatever has happened in the past has been done, we can't change it, but we can change what may happen in the future if we take a good approach now. It is in our hands whether we will regret it later in the future or not.
As for me, I have zero regrets. The only thing I felt sad about was that I didn't know about Bitcoin earlier. If I had known about it, trust me my portfolio would be reading millions of dollars through mining and earning because I had a keen interest in technology at that time. Good thing i can afford to buy with my DCA now. What's more important now is the accumulation stage i am in. Later in the future we will all be happy and that feeling of regret will never be known to us again.
I used to regret why I didn't start my bitcoin accumulation journey a long time ago, but we must not allow that to weigh us down in being consistent in accumulating bitcoin because we didn't know about bitcoin earlier and we can't undo the past, so we should move on and put the past behind. What our concern should be now is how we are going to accumulate the quantity of bitcoin we want to hold for the long term in a way that it will not stop us from sorting out our daily expenses. We are still early in accumulating bitcoin; if we are consistent enough in accumulating bitcoin, we will make up for the past we missed accumulating bitcoin and also avoid any regret in the future.
It was unfortunate for those of us who didn't invest in Bitcoin when we had the opportunity, but since there is no benefit of regretting about the fact, we need to hold Bitcoin from this point rather than wasting our time. Even though most of the people in the world have heard the name of Bitcoin, they have not started investing. That's why if you consider the current time as another opportunity and collect bitcoins according to your own ability, then after a certain time it is definitely possible to create a large portfolio of bitcoins. Especially if the DCA strategy can be sustained for a long period of 4-10 years then it is definitely possible to expect significant returns from Bitcoin. It may not be possible to get back the opportunity that we missed in the past, but if we consider the future and focus on Bitcoin accumulation from now, then at some point we will be able to get that opportunity back again.
There are people who regret for not investing in Bitcoin when it was very affordable and some said they can't afford to miss such opportunity again in their life but yet they are still letting go the opportunity later they will still regret which is a sign of unseriousness and I guess they are still having that same feeling they had some years ago, it's fine to have that feeling but it's not good to go into Bitcoin investment with that feeling because one can easily panic or sell in loss because of the market volatility which is a negative vibe but I understand that everyone must not invest in Bitcoin so anyone who think it's not good for him or her should forget about it and anyone who thinks he or she can do it then its cool.
