i feel like this coin will have a high price but wont be easy to sell due to low volume
I don't think this will be a problem as you would be selling the genesis token.
XDM usage will reduce its already small supply so, in theory, it's value will increase. I say theory as nothing like this has happened before.
I'm struggling to figure out XDM value as all my data points are tied around inflationary assets and XDM is a totally different beast.
One thing I'm sure about is XDM will see usage. If your a game dev irrelevant of size XDM is your ticket to the benefits of blockchain integration.
FYI.
