In PoW mining usually using this equipment you can mine different coins in PoS mining you can mine only that coins that you hold.
Now cryptocurrency market start to raise. So I think that the projects with PoS coins will be successful.
I think that now is a good time for listing. But a lot of depends from a choice of exchange. Exchange must have a good liquidity.
Without listing it will be impossible to attract users to the ecosystem of the coin and attract new miners.
