And another similarity is for example the huge interest of younger generations towards investments which cryptocurrencies exposed them to. The same can be said about 1918, the huge interest of the public in stocks to which they we're exposed to by Government War Bonds. Technical Analysis is no exception, the interest in Technical Analysis skyrocketed in this decade of financial prosperity. The interest wasn't there anymore after the ''Great Crash'' however. Similarly, there's a big interest of today's generation towards Technical Analysis (including myself) which was sparked by this crypto market.
Gann was either a genius, or the bear market is getting to me ;)
