Why did Tambola choose EOS? Why not ETH or NEO?
EOS is yet to achieve anything like what Ethereum has achieved.
With that being said though, if EOS is able to achieve their goals,
then it will be a significantly better blockchain than Ethereum.
I think it is very good move for tombola to choose EOS rather than Ethereum due to the fact that ethereum has more transaction and very busy, not like EOS which I can safely say that it is very convenient and less hassle for all the people who will be part of this project.
