I think the money cap should increase because I see people selling pokemon in the "buy pokemon" section for prices like $4,632,678,923 and the cap is only about 2bil. So I was wondering maybe the money cap should increase to at least 5bil.

money cap does not have to increase because you cant do much with money

You can find the pokemon in the buy pokemon section in the maps or on random swap. It's not worth buying them even if they are high level. Plus your trainer level isn't high enough to buy one anyway.

I kind of actually agree since pokemon thats at the buy pokemon section is usually more than 2B which is our max so if theres a way to increase it, it would make more sense.

I don't agree if make more trade cap money, but I would agree if make the pokemon more cheap in cash
