Whats Callisto for ? how many Callisto will be on market or will Callisto have same amount of etc  (99.4 million)  ? Is it mineable ? is it premined ? I think there is no clear information for now. If Callisto will come with real project and team maybe it worth to buy some etc now to get some Callisto. Etc can reach at least $90-$100 so easily. Hopefully etc developers give all information soon.
