I've been an active user in this forum from 2017 up to 2018. I was curious about learning new things during that time especially all about Cryptocurrency. I also tried joining signature campaigns during that time. However due to College(Engineering is hard
), I didn't have the time to study more about Crypto and be an active member in this forum. Earlier, I was checking my earnings from my previous campaigns and I am shocked that my Bitcoin did increase its value. I was wondering, what are the things that I missed and do you have any specific websites/journals/books that can help me regain my knowledge about Cryptocurrency? Thanks!
