It looks pretty but so far the only coin it carries that I have any of is QBT, which is at grossly low prices there right now (cheaper than DeVCoins fergoshsakes!) so I have not yet bothered to send any coins there to try it out.
I am running into horrible delays trying to get electrical hookup at my country-house so have not been able to explore any of the other Sci-Fi coins yet due to having long ago run out of electrical fuse capacity here in town.
Once I get my new electric hookup I can start turning on GPU-equipped machines again which will help a lot as I see quite a few of the coins are not ASIC-mined.
Long term I am quite interested since Science Fiction is a genre that should fit quite well with the
Galactic Milieu.
Thus possibly some of the coins there might well be suitable for adding to the collection of galactic currencies found at
