The thing with the price prediction are that it is not an exact science, like most traders on the Stock market are doing with shares and Stocks and also Forex currency markets. Most of these financial instruments have very low volatility, so price predictions can be made on historic data and also seasonal trends.
Yes, by contrast to crypto markets the usual stocks market is sluggish and because of that trend prediction can be a lot easier if accessing the right data.
Bitcoin is a beast ....with extreme price volatility and the smallest events triggering panic amongst traditional traders that are trying their hand on Crypto currency trading. (They are trigger happy, with the slightest drop in the price... causing a trigger affect on the market)
The early adopters of Crypto are usually more accurate, because they will make predictions that might sound crazy to traders that are coming from the traditional trading platforms.
There is some sense that the early adopters are able to make these predications with higher accuracy than the later folks but that's not to say that this is a distinguishing feature especially since now there are so many tools to track historic prices that anybody with the right knowledge and access to them will be able to interpret.
In the end, though mainly based around winnings, market prediction is also about fun and knowing you've been right and in a way it is an exciting gamble
no wonder it lifted off so qickly.
