I'm not familiar with those courses, OP. Can you tell us a little more about what they're about and why you're recommending them? Maybe we can get some more context on what Purnov's courses are all about.
I'm not sure what this thread is about, but I couldn't find any info on Alexander Purnov. Can someone enlighten me, or is this a translation issue? Does it have something to do with cryptocurrency courses or something else entirely?
