Engaging in testnet has become the order of the day as most projects are going that way now, knowing that hunters are prepared to indulge them. What most hunters expect is any free token they can hodl for the bull run. The belief is that any token, it doesn't matter what's the utility, hedl before the expected bull run will amount to something they can cash out with. It's a 50/50 thing, both for projects and hunters. In the recent past, some of the stories about testnet rewards haven't been palatable but that's what it's because projects don't say what their distribution will be like. Some of them even get to add more hurdles as interest soar for their projects and make it cumbersome for hunters. I know that won't deter the dogged hunters from indulging fresh ones springing up here and there. So, OP there's no guarantee what testnets will offer testers.
