I think you also need to have some solid coins like ZenCash, NEO, LTC or ETH in the portfolio.
You do not have to think about it. Everyone must have some of
the solid coins. Bitcoin, Ethereum, Litecoin, Neo, and many other
coins are solid in my opinion. In which coin to invest more should
be individual decision, based on what individual prefer more.
I keep saying that this market is young. Everyone should work on
making portfolios, and filling them with diffrent coins. More coins,
more different projects. Invest when ever you can, how much you
can.
