Bitcoin is a ponzi scheme - i feel bad for people who got sucked into this mania
As I said from the beginning.
Manias are an interesting lesson in phycology. I've studied all asset bubbles since the tulip mania of 1630's. The common thread is NONE of them ever end well. Those who lack logic and critical thinking skills are the ones who get sucked into these manias. Once they are in, the euphoria prevents them from seeing it's a bubble.
I still predict many who bought dipcoins at 10K, 15K, and 20K and hold all the way down will be taking swan dives off tall skyscrapers. People that do this should be given a posthumous Darwin award. Serves them right for being so greedy and stupid.
The stock market is also a huge bubble. Same goes for the bond and real estate market. Today the DOW lost almost 700 points. Expect much more of this type of action in the near future. EVERYTHING is a bubble, except for precious metals, some grains and most softs. Remember, you're suppose to buy low and sell high. Successful investing is about timing more than anything else.
