Each way to build a cryptocurrency investment portfolio will be different. Depends on several things, including time period, strategy, capital, risk taking, and our readiness. So, in this case, what we also need to underline is the risk we will take.
If we expect to invest for a certain period of time, such as in preparation for a bull run, then it would be better to take crypto that is already solid and top. because this is of course lower risk compared to new altcoins.
Personally, I try to invest more than 70% in Bitcoin Next is the top altcoins which do have the potential to rise. avoid new coins or hype clins. it is not at all suitable for long-term investment, because it carries a higher risk even though sometimes it is very profitable. stay careful.
