The game is supposed to by a crypto game eh? Haha, ya you could make next to nothing, dust, yet I still found the game fun enough to keep playing it. There is a segment called Shrine Of Trials. You progress through harder and harder battles similar to regular adventure mode. On both adventure and shrine of trials I was stuck for a real long time. I would not consider spending hundreds of dollars to upgrade the characters, I would rather play through it as normal, I think it is better for the challenge that way rather than spending a bunch of money. I really think the crypto element of the game is a total gimmick, there is no marketplace, no nft's only winning items you can trade for dust amounts of crypto if you get a high ranking. So there is no way you could make money at the game by investing in upgrades for the characters. Still if you think it is a fun enough game then play it
Here is the next level after 160 which got easier for a little bit until level 171 where it got hard again.
Here is where as you can see it got too difficult again
I don't know how much more I will play this game, I do enjoy it, yet that may wear out soon. I am still ranking in the top 65-200 in most aspects of the game without spending any money on it so looks like I'm doing not too bad. You earn more items in game the higher you rank and progress
