Hi, you might try investing in casino bankrolls (see results of my own investments in my signature).
It's long term investment but unlike ICOs you can withdraw your funds anytime (and invest them elsewhere).
thats a nice idea. how can you withdraw at any time? surely someone would need to buy them first?
The funds are still yours. Part of your balance (just sort of blocked from being gambled away). You can cancel the invest whenever you want (and gamble it or withdraw).
But e.g cryptogames games charges small fee to short term investors (you need to keep funds there for 21 days otherwise divest fee around 0.3% will be charged)
EDIT: in other words you are just lending them your funds and they are giving you part of their profit.
