Is there a github yet?
https://github.com/ionomy
I read there that the source will be uploaded on May 16th when the wallets are released.
There are no wallets? What happens to the coins you buy now? Does the team that refuses to be transparent hold on to both them and your BTC? The team that won't publish any addresses and won't use and escrow?
The coins you buy now are listed on the 2FA secured ionomy website and dashboard, just like the LISK and WAVES ICO coins are on their websites.
So they're just numbers in a standard database at this time, or is there an actual functioning blockchain?
Yes there is (testnet).
If they are selling coins how come the blockchain isn't finalized?
