I do not fully understand what the meaning of this method of mining... but in any case, if it is interesting, then you must definitely use it. Especially it brings profit, I do not know how much greater.
The main thing that brings a stable profit. This is a big plus of this type of investment. In addition, you do not spend on expensive equipment, this is a plus))
Of course, the chances are not great, if you simply fold the pens and do nothing. Then nothing will happen, and they will not get anything right! But I think that the developers are specifically focused on the result!+
