I invest in a project according to different criteria:
- Its marketcap (is there some room to grow?)
- It's usecase
- Exchanges
- Community

Sometimes i take advice from people i trust a lot. Reason is i could have missed a crucial point that my interlocutor would have understood much better. Together we are stronger !

And finally, like a lot of people here, i have some 'serious investments but also some 'poker shots'.
