What is the BLOCKCHAIN!?

I'm sure all you hear about is how "crypto" is a scam, NFTs are a scam,  it's ALL A SCAM!  I'm here to tell you that...  It's almost true. A lot of it HAS been a scam BUT there are many scams on the internet in general, does that mean all of the internet is a scam? Absolutely not. How are YOU going to use this tool?
