ok, so i read the announcement on the new 2.0 site.
from what i gather so far, this is the same exact coin, using the same exact ticker, but is now taken over by a new team.
also, at some point in the next couple of months this thing will fork at 4:1, cutting everyone's current sigt holdings by a factor of 4 (if you had 10,000 sigt you will now have 2,500 of new and improved, yet somehow the same sigt 2.0).
at some point during the fork the dev team will be allocated 28% of the total coin supply, 20% for devs and 8% for some other fund.
pow may be back in the new fork...
