Because bitcoins are illegal in my country, I'll keep my personal domains on namecheap but will certainly move my company domains out of there until I figure out if there's a chance I have problems with this. I like bitcoins just like everyone, but there are laws you need to abide by and bitcoins are illegal in many countries.
I don't see your concern being very realistic. I very much doubt doing business with a foreign company that accepts Bitcoins is illegal in any country as long as you yourself are not involved in Bitcoin trade. I mean, obviously you can be as cautious as you want, but it seems unreasonable to assume that NameCheap is forcing any liability onto its customers.
I pasted the law and even a case to some other replies, I wouldn't just throw that if it wasn't true.
