It is quite early, but if you try and throw in 100 HBD, you move the DUAT (the only asset atm) market price up tenfold. Obviously, a massive bubble Axie-style can always happen but even if it happens, the game's fund won't cash it in - the card owners will.
My understanding is the most money will flow in from fees associated with actual play (healing, tourney entries) and if the players pay 1M to play and get 200k at the end of the year, that is a lot of players down money in the first year. Their decks might be ready to fight for the next years' reward pools but in practice only a handful of them go that far while most fold up after a month or two (so good luck collecting that 1M in the first place).
Do not get me wrong - losing players play for fun all the time but it is not like they can chase a dream of hitting a big score (what poker tournament offers) nor lose track of how much they are losing because there are enough winning sessions to feel fine (poker cashgame).
