It's okay, coin should be quite cheap on exchange when it comes back because right now it is not widely known, so you can easily get some to stake. However, whether the price will go anywhere good, I do not know. Dev is very dedicated and updates often which is excellent, but the role of the coin is unclear.
I agree with this assessment. I think all of us are awaiting to find out anything more from the dev such as roadmap or his vision for what GalaxyCash is/will be. So far it has just been a plain and simple coin, nothing more, nothing less lol. He does seem to be quite active for now though, so let's see what he says/does.
