I didn't have a bad experience, but just got tired of it after a while. Here are a few reasons:
When you're an expat you meet a lot of people, but it's hard to form anything but superficial friendships because everyone is always on the move. You can always become friends with locals, but cultural/language differences get in the way.
While it may not seem like it now, your digital nomad life will eventually become predictable and ordinary just like life at home. Especially if you're working. Work is the same no matter where you are.
And the big one for me....it's hard or impossible to do a lot of things while you're nomadding. For example, growing a garden. Cooking barbecue. Fiddling with electronics. Playing in a band.
That said, there's no reason not to try it. Just don't assume it's a rest-of-your-life choice.
