What is the problem though? NIRO wallet has been up and down on bittrex (at least I've noticed) for the past few weeks. Is the issue a Nexus - Bittrex one, or Nexus alone? Or, for that matter, a solely Bittrex problem...?
As I understand, from following slack, all the problems stem from somebody mining directly to the Bittrex wallet.
So, a problem with far less than 1% of the outstanding NIRO has halted functionality for a week+ on the only exchange with any substantial NIRO liquidity. This tiny error condition could do the same damage next month, based on a small handful of miners who might make the same mistake, that NIRO cannot prevent. The exact same problem could/could not happen to BTC or ETH. The probability of someone repeating this error, frankly, is reasonably high. Somebody correct this analysis, because this is why would-be buyers of NIRO are not buying.
I believe in the NIRO development team greatly, but these are my concerns.
