If I had 10k$ I will never invest them in one coin as you said, that will be very unintelligent, I will definitely split them into different coins/tokens, I will choose 10 projects and invest in each one of them 1k$, I will make sure to choose serious ones that are still at the beginning of their roadmap, also, there should share the criteria of being unique in their goals and views about the use and integration of cryptocurrencies in our modern life, not just a copy of other projects and should have a solid and trustworthy team.
