Most people always had regrets of not buying on dip, when at 3k, coz when BTC was on lower price, they keep looking for lower and expect much lower til price increase and miss the chance. Mind you its a cycle, that keep happening but still missing chances.
So far, my regrets was my tokens on miss of selling them on ATH, just hodling till nothing lol, well that's was my newbie days.
Many people did the same thing and that I think is normal. People tend to seek for what is 'more' not being aware that they might lose everything because of what they are anticipating. It is like one missing the diamond while seeking for gold- kind of scenario. Many people would set plans but the levels of satisfaction depends on the individual. One should have discipline to all things not only on investments. The market is volatile in nature and with that being said, what is ideal is to secure the profit once opportunity knock, avoid greed.
We all have our regrets in crypto, but the most important thing is to learn from mistakes not to have the same regrets in the future.
That won't be as easy as it may sound. Many people are still experiencing the same mistakes even the best ones in any field because we won't always have that 'discipline' everytime. You would only learn something once you know how to apply that thing you have learned.
The biggest regret is that I sold about a dozen bitcoins in 2017
Tell me if I remeber it correctly but I think that was the year wherein the market prices were twice higher than the current market value of most cryptos in this industry. Unless you sold early that you also missed the ATH.
