If you want to learn about cryptocurrencies, google is your friend :)
If you want to invest in Cryptocurrencies, make sure you understand the process of securing your investment in cold-storage extremely well.
If you want to make money with writing, just make a free SteemIt account with your Facebook or Reddit account and you can start earning right away, risk free!
Oh yes, google is definitely my friend for A LOT of things.
Sadly, I don't have the extra funds to invest in anything and I'm sure I'll be peeping in on the wealth of information from a few people I'm following - yourself included!
As for the writing thing - well... I'm here. I'm writing and I enjoy watching the pennies. It's better than goose eggs, right? I'm guessing that Steemit, though monetized, really wants to focus on building community as well - which is why you'll never see me only reply "nice post" EVER. :)
