Managing our own portfolio is the best thing and wise too. Agreed. I was just checking the options, if there any such services available and i believe its a 'NO' as of now.
There is one. There's a fund called cryptomerian, and it's been along for quite a while. The founders and all are based in Turkey, if i remember correctly. Their company is registered offshore, and they are a pooled investment fund essentially.
They invest in everything from altcoins, bitcoins, ICOs to gambling bankrolls. You can buy their coin, which represents shares in their investments. Then there is Bit20 and crypto20 which is an index representing the top 20 cryptocurrencies, you can also invest in them.
This is pretty much the only one that I'm aware of, at the moment. Still though, they are quite risky to invest in since they did have some problems in the past. Just manage your own portfolio, it's much more secure and there are no commissions.
