Would you guys suggest for a beginner to focus on mining solely bitcoins? Or would you say that it's smarter to mine for the other digital currencies out there?

Yeah, I'm pretty aware of this but I'm still interested to learn at least some foundation that I'd need to understand how everything works.

Awesome! I'll check them out. Thank you! 

I'm using both but I found that I can use Google Auth on a lot of websites compared to Authy. Might have to remove my Authy because of the security risk that I've only just read now in this thread (obvs, I didn't do a lot of researching about Authy) lol!

Would you guys recommend Duo better than G Auth? Or that's a different thread? 

I'm fairly new and I've started researching about BTCitcoin and cryptocurrency. I'm aware that there are a lot of information I can easily Google and read regarding this topic, however, I find it easier to learn through videos and podcasts (especially YouTube ones) and I can't find the best ones.

Do you guys have good YouTube videos or podcasts that you'd recommend, especially for beginners? I'd love to understand cryptocurrency more as well as start learning about investing and trading.

I'd appreciate it a lot.
