Op is no need to know the percentage of each person portfolios but you can also the diversification of the person's investment. You don't have to know because that is a private affair. And as for me I am only invest in Bitcoin and Eloncoin altcoin. And the two are doing great. Though Eloncoin is just a new project that hit the market recently and it is doing well. Diversification of investment is good and it is also dangerous because altcoins are not reliable. They can disappoint someone at anytime.
