Many people speculate like that, unfortunately they are not really serious about doing it, especially if they want to do it in Bitcoin, if they did, maybe the average crypto user would already be rich in the world.
Investment, talking is easy, doing is difficult, that's a fact that happens and it is included in research, in fact we know Bitcoin is increasing day by day, investment is the best solution but that's just talk, few do it, so try doing itwith determination and strong desire how you invest.
I hope that in the future everyone can do what OP did, I hope that in the future we will understand financially the benefits of investment.
funny enough, people who sucessfully doing this are usually people who are new to crypto and just buy BTC every week or month, they just disregard the risk and keep accumulating BTC, now they comes out as a winner, some even still buy BTC routinely to this day.
it's like the saying "A person who thinks all the time has nothing to think about except thoughts.".
too much thinking lead to hesitation and lead us to potentially miss the best opportunity there is which is investing in BTC.
