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.
New people in the system always think about quick gain in cryptocurrency but with the little knowledge I have gotten in cryptocurrency things are not done that way, I have always advocate for Bitcoin investment for newbies because of its trustworthiness, aside newbies falling victim, old folks also end up making this mistake, there are many new coins no doubt but one thing is for sure almost all of them are scam, the mining process and everything they do doesn't look transparent, bitcoin as the first cryptocurrency have laid a legacy and thats why it is advisable for any investor be it old or new to always think bitcoin but if we must diversify, we have to go for coins that have been in exchanges for a long time and it should be a well known project in other to avoid regret.
