Booko is also launching its own token based on Ethereum blockchain, that will be used in a similar manner as hotel points. Booko tokens will be issued as rewards with every booking, and may be used to pay your next trip or to be traded on exchanges market.
Booko tokens are like a royalty program.
For example, imagine that in December 2018 you have $500 in LTC and 150 BOO tokens, and 1 BOO = $1 (so you have $150 worth in Booko). You want to book a flight which cost $500.
You have two possibilities: either you pay the whole flight with your LTC, either you pay a part with your LTC, and another part with your Booko tokens. You may use them anytime and anywhere.
These tokens are yours, you may decide to hold them and book flights later with them, or sell them against BTC or someting else to get your money back. It is a sort of smart royalty program.
