The on-ramp in crypto is incredibly well built out. But then, once you are in the fake money world, you will notice that the off-ramp doesn't exist.
The off-ramp of nearly all of my crypto endeavors has been very easy in my experience. Not always simple, because a lot of parts of moving money on various crypto chains is unintuitive and well in-need of improvement, but definitely easy once you know what to do.
The most annoying part, somewhat surprisingly, is always with regards to United States KYC restrictions. I've had a fair bit of annoyance trying to move crypto off of services that were once accessible to US customers and no longer are.
I have taken money out of Polymarket and it is quick and easy.
on-ramp and off-ramp were the problems of the past. Thanks to Trump, both worlds have merged together now.
Offramp exists it just depends how ugly it is by country. A friend of mine literally travels to another country to withdraw what he is paid in crypto.
