I have a bitter experience in this regard. Before learning about Bitcoin, I invested in shit coins and my losses were very high. I held a few shits and had high expectations from them. But over time, I had to lose that investment. In the long run, I only regretted it. If I had invested in Bitcoin for a long time, my wealth would have increased over time and I could have been more optimistic in the future. But I was able to change my situation a little late. I now believe that only Bitcoin is the best. Whatever its value is, if it can be kept under one's control and accumulated according to the ability it is definitely possible to achieve financial success in the long run. If DCA is followed for accumulating Bitcoin, then anyone can expect big returns in the long run.
I have a similar story as you in that I also invested into a lot of shitcoins when I started, some during their ICO stages and others in exchanges already where they were reading and being hyped by scammers and those ignorant of the scheme. I lost miserably and whenever I look at my wallet and see those worthless shotcoins, I still feel bad.
Joining this forum and following the advise of experienced people like JayJuanGee changed the game for me because I'm now only in Bitcoin with no regards for whatever the shitcoins out there does. Bitcoin is just the way to go and those who will diligently accumulate Bitcoin and hold will be handsomely rewarded in the future.
