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.
