I don’t think NuBits promises this at it’s early stage.
Converting larger amounts of NuBits does not work necessarily on
a) the same exchange
b) at one time
at these, quite turbulent times for this project.
Nu promises to to buy back for 1 USD, but not when and were exactly. It’s a main goal to reach this, but Nu obviously can’t afford it atm. Patience and solid growth are needed, more than ever.
