Your wallet address is the address of the NEM wallet, why not consider developing your own wallet or eth address? I think the NEM wallet for a lot of people a bit unfamiliar, of course, you may have your consideration, perhaps I NEM Poor understanding of the wallet. Of course, this time involved in your activities may be a good opportunity for me to know NEM wallet, I will download one now.
I don't see any reason to create a new wallet in the near future , if the NEM wallet is working fine. People would also rather download a wallet that has been proven safe i think. The focus should be on the technology imo.
Yep, it is all about the technology.
It's kinda like saying... don't use Ethereum wallets for an ERC20 token... Which doesn't make any sense whatsoever.
But as mentioned in the OP, NEV will start out as a NEM asset and later be swapped to XEV with its own network.
