Hi guru2class!
First I want to let you know that I appreciate your effort in educate other people about crypto and how to build new cryptocurrencies/blockchains.
One suggestion is that you can try to make your videos to have a better quality, for example: "Learn How to Create Cryptocurrency Like Bitcoin(SHA256)" hurt my ears in the beginning and my eyes all the way I watched it.
I hope you'll take this as a constructive criticism and not as an insult or anything like this. Anyway keep doing what you started eventually you'll get better and better. I wish you all the best and I hope your channel will be successful.
