If you are not satisfied with the level of your achievements, then try to fix it. Change is impossible without trying.

Need to be content with what you have. Many don't even have that.

Not all bitcoin investor stories have happy endings. Many of them made various mistakes, because of which they lost their btc (= money). Forever. Therefore, the past should not make you unhappy. It's not a fact that you would have been able to keep btc all these years. Take it philosophically: you learned about BTC and encountered BTC when you were ready for it. Not earlier and not later.

Exactly. Such phenomenal profitability from bitcoin, as it was in the initial periods, will certainly not be. You shouldn't be sad about this. With btc you can increase your wealth even now - thanks to high volatility and high returns.

Those who are looking for opportunities will definitely find it.
