Well, there are captchas that are unrecognizable but if this prevents the TH from going up like crazy, it has my full support. With a little dedication, I'm already getting the hang of it.  
Good jobs, devs
Although I'm curious to know how many captchas I've solved, I've already lost count.

Edit: Has anyone received xrb in their telegram wallet without any problems? It's just to make sure.
