I'm just looking for a hardware wallet. But I still do not see the answer, why do you need your own coin? After all, you can use the network of ether.
As far as I can understand own tokens issued to provide tokensale and collect money for further development.
Or did you mean they planning to make own blockchain?
I find it advisable to promote a hardware wallet without its own coin. But now it's quite popular to make a coin. For marketing reasons, I understand why this is necessary.
