I'd like to know about BURST mining:
What is its profitability, what are requirements to start mining? Where can I find any manual how to start Burst mining if my calculations will show any profitability ;-)
Thanks in advance

You'll need high capacity hard disk drives, (8-10tb) and a pc. Nothing else pretty much.
If you are going to use external hard drives like me (I use 3 8tb and have been mining for a year) you'll also need a powered usb hub.
There are 2 things you need to know. Your pc should have a usb 3.0 if you are going to get the external hard disks and your CPU should support AVX2 architecture if you don't want slow ass read speeds. (Means you need to have intel i3 or higher)
Profitbility is pretty shit but considering that you don't really spend any electricity it is doable as a hobby.
Like i said I've been mining since last year and It is all going down since then. Buy and hodl usually a better idea.
