It can be seen from Fig 6 that coherence in the short run is erratic throughout the time interval analysed, and that there is little appreciable difference between the bubble and non-bubble regimes. However in the medium term (8–16 and 16–32 days), coherence generally peaks around areas where bubbles have been identified in the price series. The longer term relationship, though, is less dependent on whether the price is in a bubble phase.
We’ve seen Bitcoin hit multiple new all-time high prices, regulatory talks with potential to have big impact on the industry, and more institutional buy-in from major companies. All the while, people’s interest in crypto has skyrocketed this year: it’s a hot topic not only among investors but in popular culture too, thanks to everyone from long-standing investors like Elon Musk to that kid from your high school on Facebook.

The most popular cryptocurrencies are currently Bitcoin, Ethereum and Litecoin. These dominate the cryptocurrency market and are highly popular among traders and investors.
If this type of extreme drop bothers you, you may have too much riding on your crypto investments. You should only invest what you’re OK losing. But even if the drop is making you rethink your crypto allocations, the same advice still stands — don’t act rashly or upend your strategy too quickly. Reconsider what you might be more comfortable with going forward, such as allocating less to crypto in the future or diversifying through crypto-related stocks and blockchain funds rather than directly buying crypto (though you should still expect volatility when cryptocurrency markets fluctuate).
