I wouldn’t advise that you take investments, especially one that requires you investing a large part of your portfolio in any other coin other than Bitcoin.
Quick gains are mostly attractive to new investors who consider that they should be able to make profit from cryptocurrency, just the way early investors in bitcoins have. These new investors completely forget the strong foundation that bitcoin has and go for new coins that they believe can blow up quickly for them to make maximum gain from. New investors who are always focused on investing in new coins will mostly be victims of pump and dump schemes.
It's natural that this happens a lot to novice investors, because currently crypto and bitcoin investment has become a trend, especially among young people. Where they compete to generate profits through the investments they make. But as you said, it's a shame that some of them "forget about the strong foundation that Bitcoin has and look for new coins that they believe can explode quickly so they can gain maximum profits." They are really in a hurry to do everything, without doing a further analysis first regarding the coins they are going to buy so that instead of making a profit, in the end the investment they make only results in losses.
So it is quite important for us to spend a little time just studying and understanding the technology and intrinsic value of each crypto asset before investing. And by focusing on long-term investments and choosing projects that have a strong foundation, this can help us avoid fraud schemes and maintain profits in the long term.
