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.
Almost Everyone has had such a sad and tempting experience, most investors were initially interested in such shitcoins hoping to get more profit, where they invest their hard-earned money and in the end get only disappointment as a result, but they have understood the right thing over time and are currently holding Bitcoin because they are interested in Bitcoin. But what is even more sad is that at present all new investors are making such wrong decisions, the mistake that old investors made at first, new investors are currently making the same mistake, current new investors are becoming interested in shitcoins as an investment to get rich overnight, at this moment they should try to understand the right thing, shitcoins will never give anything good, Rather, whatever you invest here, after some time it will disappear, so if you don't want to lose money to this scam, you must choose the right investment and only Bitcoin is the right investment as a long-term investment.
Investing in shitcoins is not a mistake I consider that as an error because most of them, if not all of them knew that investing in shitcoins can be very tragic most times and the reason why I said most times is because over the years we have experience more losses than profit. Moreover, shitcoins can give profit no doubt but it is very rare I mean it doesn't happen or occur frequently and so the best thing to do is to avoid anything shitcoins unless maybe an investor has gotten to an overaccumulation stage and then wants to diversify and I still don't consider that as a good option instead the money an investor want to use and diversify in..., can still be used to be accumulating more Bitcoin.
