You mean getting stablecoins off an exchange?  Why not convert them to bitcoin and spend that?  

I never saw what the big deal is with them anyway except for keeping your funds on an exchange at a stable rate.  That's what they're good for, right?  I don't think anybody really wants or needs to spend them, nor is there any advantage in holding them unless you plan to trade them for bitcoin or something else.  Nor do I think merchants are ever going to take coins like Tether.  We're having a hard enough time getting businesses to take bitcoin, much less stablecoins.

Well, that should work for OP if it does what you say it does.  But it just seems like an unnecessary step to even own a stablecoin--maybe I just don't get the point of them.
