The value that I see on them is you're taking care of your health and you're obliged to move and walk. Just think of it as something forcing you to have exercise and the benefits of it to your health is more than what's the value of those tokens. That's the best consolation or worth that you can think of with these apps and projects. But if you think that they're not worth it, then just walk or run alone without being tied up with these apps but honestly, they're a good motivation for someone that's looking forward to become healthier. So if you've got goals to live with these apps and tokens, that's your decision but you can live without them as well but keeping up with what they're promoting and that is to move.
