yes, I have been an ICO investor mainly during the bull run in 2017. Basically I am starting again on the sidelines with the extra cash from leverage trading. these are some projects I invested in icos: KNC, NEO, ICON, VEN(VET) and LINK. Back then it was projects that empowered fast transcations, trades and dapps.
So It's been a great ride for me and similarly next gen protocols for 2021 would be NFTs( SuperRare, Nifty Gateway, Rarible), DeFi space(ALPHA, AAVE, MAKER) and solves scalability(DOT, ATOMs & NEAR). Hence Protocols like TERRA and Persistence stand out with their products.
