That’s just part of the loyalty rewards.
You are under no obligation or pressure to buy any AVA. I wouldn’t exactly call a working product a shitcoin, it’s getting bookings Daily and making actual real world revenue. I don’t think the same can be said about many projects around right now.
Anyways, the point is you use over 40 crypto tokens to book with and don’t need to hold AVA. https://www.travala.com/payment-options
For example you can book with bitcoin and you get some rewards for using the service back into the internal wallet using AVA.
Next time you book with BTC or whatever coin you use you can use some of your AVA token to pay part of the booking or you can just save it up to get the different reward teirs.
Next time you are going on a holiday why not take a look at booking .com or whatever hotel site you use and compare the prices. You can even book with creditcard if you didn’t want to spend your Crypto.
Pay with FIAT, get rewards in Crypto token. Easy.
