You invest in Top coins, you diversify with investments in some of the alt-coins. It`s how you start building crypto-portfolio, where Top coins should be
at least 60% of your portfolio, the rest is diversifying.
Ratio is good as long as you believe in it. Some people believe in alt-coins more than in Bitcoin, some are Bitcoin maximalists. I`m somewhere in between,
I like Bitcoin, and I like my alt-coins.
Making top coins your major priority and major coins in your portfolio is even diversifying to me, because those projects that are just lying fallow there without growth is not called diversification to me, it is just called waste of money, energy and time.
It is when you fully invest in those top altcoins that I can really verify that the investor has really diversified, and to me, when diversifying, one has to make bitcoin as the major crypto in the portfolio, and that is what should earn the 60 percent that you talked about, and maybe the rest 40 percent can then be for those other top altcoins you talked about.
This is the type of portfolio that we can say is really prepared for the future, because we have to ensure that we guide our investment jealously and that is the only way to guard it.
