Where can you on ramp alot of money?

I’ve come into some nice money do to farmland sales and I wanna invest more in crypto. But I don’t know what platform would allow you to on ramp like 50k. I use netcoins and bitrue, generally on ramp with netcoins then send to bitrue but netcoins has a cap of 30k a year .

EDIT: I am in Canada and I feel like we get fucked for on ramp
