Anyone noticing new projects still raising millions of dollars? Mohash and Dynamic for example, I think new projects will replace lots of top altcoins in coming years and my advice to young investors is to find new projects to mix with their portfolio, remember that Matic, Polkadot, Avalnache are once all new projects in 2018/2019..
I don't think Investing in new projects is the problem, investors invest in older projects because they are already established in the market and most new projects end up failing shortly afterward. Investing in crypto is always risky and if you want to push your risk, you can invest in a new project and hope they do well and not because there is some guarantee that they will b'cos they said so in some whitepaper.
I think just because it is a bit risky to invest into crypto, doesn't mean that you should take on even bigger risks. Like bitcoin is risky enough if you ask me, why go buy the silly shitcoinmemetoken or whatever and take on even bigger risk? Just realize that we are not going to be doing something risky anymore by investing into bitcoin and that should give you all you need to know.
There isn't really anything else you need on this. Sure you could go with a higher risk and higher reward situation but that would be not so smart. If you go that route, you shouldn't be shocked about losing all of your money there though because the lower you go, the riskier it gets.
While it is true that bitcoin is risky enough already the main reason people decide to invest in all of those altcoins even if they know that they are way more risky than bitcoin is because they think that it is impossible to obtain fast profits with bitcoin anymore, and that the magnitude of those profits is also going to be on the low side, so they prefer to invest in altcoins as they think that is the way they are going to become rich quickly.
However we know the truth, we know that the majority of altcoins will never reach anywhere near the potential they claim to have, and while some people can make money with those altcoins the majority of those which elected to trust in those coins will lose their money, and when that happens they will regret their decision to trust in those developers that were behind those coins, but by the time they do so it is too late to do anything about it.
