That's crazy honestly, what if my rig can only do 50$ per month will I have to pay 350$ every month? It doesn't make sense, the billing should be based on what miners are earning, I'm glad I'm not living in such country
That's it, so you have to calculate very well the numbers before running any professional activity on your own, or business, here. The decision to add "crypto mining" to the list was more by ignorance that reasonably justified.
In most other countries your pay is based only in your earnings, or have a very low fee in order to be able to work, and it is something that we are asking for since ages here. But, on the other hand, we have quite good social security services, which I do not know to what extent justify the expense.
