The Bitcoin bull market since 2010, appears to follow the structure of the Dow. This in itself is not unsual since it is very common for goods (commodities, stocks, currencies, etc.) to have a similar trading (or market structure) but with different timing:

Bitcoin appears to be trading in a long-term channel just like the Dow did. The Dow started its bull market in March of 2009, whereas the BTC bull market started

around August 2010. If Bitcoin continues to follow the structure and duration of the Dow bull market, then Bitcoin could see a peak around the beginning of 2020.
