People who don't believe in Crypto (the technology) are those who are mad they didn't get involved early. Now that the train has left, they are all trying to find ways to get the next train to cryptotown.
You've seen a lot of reversals on crypto from the banks and hedge funds. Pay them no mind. I believe that the technology will result in the greatest RE-TRANSFER of wealth back to the common-man(or woman).
That's why they are mad!
