Channel partners key interest is tapping into the benefits of the crypto world and blockchain services within the industry.
Hence why the following questions:
Which currencies should be accepted as method of payment?
Which blockchain, smart contract or Token based should be used for the VIP Membership?
No offence taken Snail2, But this is why Blockchain based membership could be viable for transparency and limited supply.
Which to the member provides benefits within itself.
It's straight forward to get the member discounts you need to be a member, hence the privileges and benefits.
Principles are based on the membership being trade able incase you no longer want the membership you can sell it on to somebody that wants it.
The benefits are as listed in description. (can be paid in Fiat or crypto) Hotel or flights etc
Sorry, in my previous experience travel clubs with tradeable membership quite often turned out to be such things. I do apologize if your site isn't one of those businesses.
So, is your site a crypto gateway to existing travel services (like travelsupermarket in fiat) or you have your own contracts with providers?
