It is just a game of risk management.
You buy some risky assets, some less-risky assets, some solid assets, some barbaric relics... All has its spot in the game.
Sounds about right to me. I always get a chuckle on these boards when posters (present company excluded of course) recommend diversifying and their idea is to buy as many different tokens as possible.
There is some validity to diversification, but the concept is taken to an extreme with shitcoins, and there seems to be hardly any justification to diversify into shitcoins.
Another thing, the concept of diversification is to attempt to diversify into assets that are not likely to be correlated and represent some fundamental differences. Frequently altcoins are merely following bitcoin, so they are not really a different asset class.
Finally, there is a pretty god damned low probability that any altcoin would be able to take over the slack if bitcoin were to fail, and so a justification to diversify into a world of altcoins based on a kind of bitcoin failure theory has a very faulty premise.
I am not opposed to people coming to their own conclusions regarding what kind of diversification would be good for them based on their personal situation, and I understand the temptation to completely diversify out of traditional investments; however, if an employer offers any kind of 401k, it would likely be a good idea to invest into such 401k at least up to the matching funds (if matching exists) and perhaps up to the tax deferrable limit, but that might be a question of how much money would be left to invest into bitcoin, because most young people should consider having some investment into bitcoin, even if such bitcoin investment only ends up being 1% to 10% or so of their total investments.
