To add insight, please also chart the Holland Tulip Bubble, as well as prices of Pokemon cards and Beanie Babies. May take time, but likely the latter two will be ultimately worth far more than all the current approx 18,500 different cryptos -- combined! I can't wait for the movie.
Seems like only top 3 are real drawdowns. The rest seem like corrections. Seems like the 2013 was a good year for trading BTC. Was that the year of the Mt. Gox collapse? More adoption seems to reduce the drawdown which makes sense since it would add liquidity to the instrument. I bet the drawdown this time will be less than 2018 so call it about 81-82% which means about $12.4-13.1K/BTC.
Going up from number three to one we see each time a bigger drawdown and also a longer period. Number of days to new highs is increasing too, for as far as the numbers are available. Crypto fans posted all the time that those who did not buy would miss the biggest wealth creation in human history. I think that those who did not buy the last 1.5 year are very happy with their decision. Those who did buy might experience maybe one of the biggest wealth destructions in human history.
I've been calling it monopoly money, never bought it. I like the play money in GTA5 better. Looking for a bounce someday, will likely go long COIN MARA RIOT when price action is there.
