I think in my opinion, one of the bottlenecks here is that not many gamblers are comfortable using tron network. Usually, they are oriented with btc, ltc, eth or doge. But I think once they orient themselves in using tron network, it would be easier also. They are just not used to it. One game that caught my attention here is Odin, so will be checking that out.
Thank you for your feedback.
We are going to add new crypto in nearest future. We understand that many players have not used Tron ever.
