Well, you can still invest on some altcoin but at least the your portfolio should be like more than half on bitcoin, just saying.
This is actually called a diversed crypto portfolio. If we are talking real portfolio ratios, 25% should be in fiat, 25% in Bitcoin 25% in altcoins and 25% in land or some medium risk legacy investments. Altcoins have the highest gains and risks.
There's nothing good as diversification in the world of cryptocurrency because of the risk that's involved either in investment and in trade. Last year i lost some reasonable profits from some coins because i refused diversification of portfolio and ended at lost. Your portfolio rations are pretty much exciting as i assume that will yield more profit at the end.
