Johnathan I think,that you don't understand me right. I am on really low level of computer engineering. We prog on assembler, we learn how CPU works and etc. Building PC from parts is easy level.
About cryptocurrency. Yes,they are popular. But it is popular like way to make money fast. A lot of people know, that cryptocurrency can make real money fast, but only a small part of people know,how to do it. As for me, I think that it is good thing to pay something in internet and nothing more. Blockchain is empty hype technology, and I bored to hear about Blockchains from teapots.
