I found out the price of XCT on forkdelta was cheaper than the IEO price -10000%. Really too cheap, why is it so low? Is there anything hidden behind the project?
long before xCrypt held an IEO at IDAX they first held a bounty campaign, and maybe the ones sold at forkdelta are now bounty tokens

Not from bounty. When you check carefully, you will see that the seller holds 2M tokens (a high possibility of buying a private sell). He sold out and kept 100k tokens. Bounty has not yet received a token, so selling is not possible.
