I bought TNB for 30% of my position，20 % cent of the position bought ethereum，50% of the positions are in bitcoin，How many assets can you achieve in the next 10 years 
The bull market has been here for several months now - look at how much the prices have risen since February.
I'd agree it's good to have high percentages in both bitcoin and Ethereum, there is a reason these are the top two in market cap. It might be worth taking a small percentage and investing that in some more speculative smaller coins, where there is potential for bigger gains - but also if you only put a small percentage in it won't hurt too much if the prices tank.
That's just me though, everyone has their own preferred approach.
