It may, however, survive as a "dark currency" that's used by criminals. The challenge would be to somehow convert your NXT to XRP.
What have "dark currencies" got to do with criminals ?
For a start, criminals don't use crypto, they use the US dollar.
Secondly, most people in the world prefer to keep their banking details out of the public domain. Whether the accounts are anonymous is beside the point - the transactions are not. If you're saying that makes everyone a "criminal" then I don't think you've thought very much about this issue.
Thirdly, commercial entities such as retailers, service providers and manufacturers consider cashflow information to be competitively sensitive. Are you saying that makes them criminals as well - the whole lot of them ?
Please people put 2 brain cells together before opening your mouths and letting your bellies rumble about this "anonymous cryptos are for criminals" crap.
