Understanding The Blockchain - part 4

When we are in a bull market, nobody has time to learn anything and everyone is in a rush, but when the bearish market comes around, its a good time to add to our understanding of the space, in that spirit I prepared some videos in my native language which is Persian, to help people from my country actually learn the basics of blockchain technology, these videos were published on www.coiniran.com
I always appreciate your support
