I think it would probably be better just to straight up sell subscriptions, and possibly limit how many you can have active at a time. Making it a token/coin just makes it more complex, for basically the same thing. I might buy a subscription, but not if I have to buy a token.
What is your reasoning behind making it an actual token?
Lets the market decide the price of the arbitrage betting signals.
Price will rise to a level where only a minority of people will be able to afford to engage in arbitrage betting. - Completely determined by the market
Otherwise I'd set some arbitrary price, and would have to continuously poll my users regarding how much they make from arbitrage betting and how much they bet on average, so that I can offer a price that makes sense, and figure out how many users I should accept.
This allows for an automated, market-driven, fair and generally more efficient solution.
Let me know what you think

IMO the approach sounds very good but the incentive in any case will be your stats and the success of your signals. you said it is a comeback so what were your stats before?
good luck
