It's good to do deep research on a project before you decide to invest or not, sometimes you might be wrong too. The fact that SERO price increased doesn't make it outstanding, I prefer looking at the products on ground thoroughly and the project development. Well, for sero, I rate it average since it has fair project development.
I think the SERO price increase is simple because it has a low IEO cap of only $ 250k, while the Gate floor has a huge amount of investors.
