I think there is a logical reason why they are not picking up other altcoins right now to continue with this, if they have been doing this for this long that means they want to do it with the coin they got and not move it. However I do believe that having multiple ones could make it a bit more interesting, more profitable? I do not know, it may not be as profitable because even on tron, there will be people who gamble bitcoin and even though bitcoin and its blockchain has some problems (and had some in the past) it is still the number one that everyone uses so I kind of understand.

These guys has distributed so much money so far, they know what they are doing and even though I agree with you and I think that would be best for "me" (and obviously you) apparently that is not what is good for the business and I understand their logic, I can't expect a place to do whats best for me, they will obviously do whats best for them.
