Thinking about analogy with roaring 1920s, we had roaring 2010s of rapid crypto rise.
Then there was gold act of 1933 confiscating huge profits of everybody who called Federal Reserve stock market pump scam and were smart and bold enough to invest in 1920s, sold on top of 1929 and bought gold.
Then there was securities act of 1934 making sure that such smart, but poor people don't become rich through investments ever again.
Since evil legacy from 1934 is still in force, the only piece that is missing to repeat the history is confiscation of huge profits accumulated by crypto enthusiasts who called Bitcoin and many other scam pumps, bought tokens during roaring 2010s and sold on top in December-January 2018 ...

God Bless America and don't let that dark history repeat.
