From that 24%, half 12%.
Example, for 1000 AVA locked into Smart2, you're getting 10 AVA + 17 Travel credits (10 AVA *1,7$ = 17 Travel credits). Remember that those Travel credits are pegged to the dollar and you receive more/less depending on AVA price.
And yes, of course. That 10 AVA that you're receiving monthly (~110K AVA month between all smart users) are coming from reserves of the company. Travala will have to buy this AVA's from the open market in order to be able to satisfy this need (or lower Smart %).
So yes, you guessed right.
