CryptoCurrency for Beginners

I'm over on Facebook and reading through the posts.  One jumps out of me reading a sign stating they do not accept cash.  I'm laughing at myself because I see this coming.  I'm thinking to myself I have to start taking this more serious.

I put out a comment if anyone is learning CryptoCurrencies?  Someone response sharing how they love cryptos!

I'm like finally maybe someone will give me some leads.  I was advised to join some facebook groups.  I searched cryptocurrency on facebook and found all these groups.  I joined them all.  I figured I would weed out which ones I line and stick with them.​
