BitCoin.... tulip mania new millenial style.... Some people will loose every cent they put into BitCoin.... with one stroke of the pen, congress can outlaw BitCoin... the shares become worthless.
Earlier this year, China outlawed BitCoin because people were moving money out of China and into other countries to store their wealth... that's what people do when they loose faith in their government...move money to a country with a stable government with a rule of law and a stable currency... hence the reason money is flowing into the US from Europe... mainly Spain, Italy, and Germany.
BitCoin bottom line...? Going to make a great short...and that's how to make the big money playing BitCoin. (BitCoin currently over S11,000)
