price predictions are impossible to say in the short term
but next year will be likely the most important year for tau
if this project takes off, it'll be a top 3 crypto (to put it lightly)
it's very possible to see x100+ next year (as it's only sub $100m market cap right now)
but of course it's also possible to lose your money, no one can be certain

I will say that spending a bit of time to look into it might be the best thing you'll ever do for yourself
