I have 2956 WTT token, batch 4,  received finally earlier today.
I would be interested in selling. best way would be to use  an exchange. I see that HitBtc is rading WTT , but when i try to load them there it says:

Please note that WTT is an IOU for future issued token. Until the token is released withdrawals and deposits are unavailable. Please accept our apologies for the inconvenience.

therefore i can not sell mine, i can just buy this I owe u ticket?
It's strange, as the token are released (batch 4 just recently, but earlier batches are available since earlier)

Any suggestions?
