Just came to my mind and wonder to share with the community especially for newbies.
A wrong (Altcoin) selection would destroy your dream.
You may order how? I will share my experience then you would realize the concept. I can't recall the exact date but most probably it's the beginning of 2018 when Bitcoin started dumping. I was a newbie in trading and holding. Somehow it's come to mind since I am not a good trader I should hold the coin for a long time. So that I can multiply my (Bitcoin) portfolio. I did the same as what was in my mind. Rather than holding Bitcoin, I moved to altcoin. I select two altcoins for investment and holding. And almost 1.5 BTC has invested. It was my first mistake.
However, a few days it was good for me. But when happen massive Bitcoin dump all altcoin start dumping. The dumping speed was more than Bitcoin. So I didn't bother to sell due to the huge dump. It was my second mistake what I realize now. Then suddenly Exchange announced delist for one of my holds altcoin. Means I lost too much here. Then I sold that shitcoin and add a few more QTY to my other holding. That was my 3rd mistake. As a result that shitcoin value is less than $1K. I don't bother to sell this shitcoin still now, just leave it as it is.
So my wrong (Altcoin) selection lead me to break my dreams. If I were just left Bitcoin rather than move into altcoin then I should be in a good position today. Now 1.5 BTC is worth too much especially when it was above $60K.
I hope newbies can take a lesson from this story. It's not just a story, it's giving me pain sometimes when remembering it. So when you think something similar, please select the best altcoin otherwise just stick with Bitcoin. Research the market as much as possible you can during the selection of altcoin investments. And don't repeat the previous mistakes that I have done.
Best of luck to all of you guys.
