Simple story of a guy' that is a freelancer here sometimes ago who was arrested for something else but caught up in the web of tax invasion, in his own case he have tax invasion but he was able to get a good tax legal team he was billed to back pay all the tax and he was lucky that he was able to afford that at that time.

So my conclusion os why not go ahead and lay tax on your cryptocurrency incomes, this way you can be confident with your cryptocurrency dealing, and be rest assured you get no problem with the tax Master.
