You are incredibly exposed to the same risk that these exchanges have.
How do you handle refunds? Converting twice? Sure, charge users for it, you'll be driven out of the market by businesses who are not scared to keep a crypto wallet liquid.

Even if crypto catches on more than it has, I do not think everybody will want to deal with it. I am do not do any importing or exporting. Dealing with another currency just seems like wasted energy.

The thing is, crypto should be much, MUCH easier to deal with, we just don't have mature software/UX around this. Because we're still figuring out best practices, and people are learning about this tech.
