At least according to what I have observed, the crypto market seems to behave in an absolutely abnormal way compared to institutional markets such as the stock market or the forex market. And that is why it is so difficult to predict with a certain degree of certainty the future performance of cryptocurrencies.
I think the stock and forex markets move so much differently from cryptocurrency because they have much more liquidity -- less volatility -- and because of the nature of fundamental analysis. The effect of BLS nonfarm payroll statistics on the forex markets, or earning reports on individual stock prices, can be profound though often times predictable. In the Bitcoin market, we constantly speculate about "whales" and regulator decisions and metrics of adoption that are really hard to quantify, and that's in the context of low market liquidity. The altcoin markets are even more intense; riches are often made and lost based on utter speculation around vaporware.
If I were to draw comparisons, I think the markets most comparable to cryptocurrency are decentralized assets with elastic supply and demand. Things like precious metals and crude oil. These are highly emotional and volatile markets.
And that is why, undoubtedly, any attempt to use the old indicators of technical and fundamental analysis seem absolutely useless when analyzing the crypto market.
I'm on the fence about this. I follow some consistently successful traders who live by TA. Fundamentals are really hard to quantify, though.
