Aaaand we have a first comment to answer, that probably reflect the attitude/feeling of part of the BTC community :
I’ve played around with this and it feels like a potential ponzie to me.
They (who?) sell nubits for dollars to release nubits into the wild and so someone (who?) is holding the market cap’s worth of dollars somehow on an exchange somewhere (where?).
nushares seem to exist to obfuscate this simple fact - for every new nubit released someone (who?) gets a new dollar.
Instead of ignoring this, we should try to understand why its is perceived this way and what can we do to inform. Until this skeptical wall of accusation goes away, we will not be able to move forward as much as we should
