If you are semi-professional trader this kind of trading/investing is applicable to you. Separating the amount of investment in bitcoin and in other cryptocurrency is bright idea and it seems many traders also this strategy. It seems that the OP already have background on how the market works so basically he can now make the right decision if he going to split his investment.

Wherever they invest it is still end up in a good result as long you know where do you invest. Splitting your money is a good idea but still, sticking in investing in bitcoin is best way to earn huge profit.
