Tombola is looking very likely to succeed, it is amazing how the project is full of too many dedicated Chinese people and it is clearly evident that projects driven by Chinese teammates really fare better in most cases than most other ones on the blockchain. Am still going through their whitepaper for more details. From what I've seen so far, it is a cool project.
really what you say, I also feel no doubt about the Tambola project.
and so far,
Tambola is the best project in my opinion.
