There are too many categories of ICO,
Said they are bound to a certain kind of product,
As you said CWEX,
He bound the wine,
In other words, the wine will have a certificate at the CWEX exchange.
But what is the voucher?
Most are fabricated out of thin air,
That is,
The exchange may not know the wine merchant,
but because famous for that wine,
So he list voucher of wine on the exchange.
So the voucher - can only be regarded as a name for the wine in the block - only for blockchain.
The exchange did not get the actual trademark rights of the wine.
Unless the exchange can present his voucher = the trademark right of the wine,
For example, if the trademark of the wine is worth $1 million,
CWEX's voucher = shareholding of trademark rights,
That CWEX's credentials are of real value.
otherwise,
CWEX's Portuguese wine voucher is just a trading method on the Internet.
If one day - CWEX's wine certificate is extremely valuable due to the hot transaction,
The wine merchant say that the name on the Internet should also be her thing, because the wine merchant owns the actual trademark rights of the wine - so he advocates CWEX infringement, I fearing that CWEX's wine certificate will immediately dive.
