I recommended this to several of my blockchain customers but none of them listened. I dont know if that was motivated by greed or something else.
According to Game theory there is no benefit in not selling the crypto for fiat: if you raise lets say 10million during an ico (typical amount raised 6m ago), there isnt much you can do with 20M (i.e you keep the crypto and it doubles) that you cant do with “just” 10M.
However, if the crypto crashes, and become 5M, you are going to have a hard time explaining to stake holders that 5M just disappeared...
At worst you keep 10pct in crypto if really you want to keep some upside to crypto but thats it
