If you are studying an investment opportunity, what would you need to see there to invest on it with a really significant amount of your funds, even having to sell some of your alts or BTC?
I'll never invest everything in a single project, no matter how good it looks.
It cost me a lot of money in the past not investing most of my portfolio in projects that turned out great but playing it somewhat safe saved me a couple of times.
It is the same case for me, I never go all in due to bad experiences, also because you no matter how good it looks, you alway have incoplete information on this sector.
