Lee has a record of success when it comes to predicting bitcoin’s price movements, according to Bitcoin.com. He accurately intuited the rally over $10,000 last year, for example. Now, while many investors are wondering if cryptocurrencies have run out of fuel, Lee remains bullish.

Part of the reason is his “Misery Index,” which ranges from 0 to 100 and uses contrarian economic indicators. It incorporates many different market factors, such as winning trades and volatility, in its considerations.

As of early March, the index was at 18.8, the lowest level it has experienced since 2011; Lee suggests that the lower the index figure, the better the investment opportunity for investors. “While short-term the low points are a signal of pain, long term it could be a great entry way into bitcoin,” he explained.

Why Is Bitcoin’s Misery Index So Low?

Lee points out that “it is really uncommon to be this miserable owning bitcoin,” suggesting that it has only happened a few times before. Why might investors in the leading cryptocurrency feel this way?

One major indicator is that prices of bitcoin have flatlined, falling from a high of around $20,000 late last year and then stagnating early in 2018.

Along with this stagnation, which has infiltrated other parts of the cryptocurrency world as well, investors are now beginning to wonder if the cryptocurrency bubble has popped or if it will pop soon.

Nonetheless, Lee believes that those steadfast enough in their investments could see a major turnaround. He believes that bitcoin prices could climb to $20,000 by mid-year and that it might reach $25,000 by the end of 2018.
