No matter how long you keep advising some of these people not to invest in shitcoins they will never listen till when they eventually fall victim of rug pull in projects that doesn't worth investing on. I keep wondering what usually motivate them to make such decisions. Why not invest in Bitcoin and relax, some want to get quick roi which is not a guarantee at the same time expose themselves to high probability of losing their capital invested in these shitcoins. Since I know Bitcoin investment, people who invested in it and hodl for long always win. If people always win in Bitcoin investment in the end why won't ever investors both new and old just stick to Bitcoin alone.
We also cannot force them not to invest in shitcoins because each person decides to choose their investment. If they are still comfortable investing in altcoins, they will continue to do so even though it will be difficult for them to choose the altcoin because there are many altcoins on the market.
Even if they become victims of scam projects, they will not stop investing in altcoins. They still see altcoins as a driver for profits. Well, that's fine if they can find the right project. But it's not easy to find the hidden gem.
And we better stay focused on investing in Bitcoin because we may not have it for much longer. So as long as we still have time, we must keep doing it.
