The cryptocurrency market is very unpredictable and is not similar to any of the previously created by mankind. It is almost impossible to predict the market.
You are right that the crypto market is not like neither the stock market nor Forex. But I think it's because the crypto market is still very young. Over time he should morph into something similar serious with clear rules of the game.
the fact is that the cryptographic market is very subject to manipulation by humans, the so-called "whales" - and they manipulate this market at will, and now hold the market down to create panic and buy more coins from smaller holders, investors, and bounty hunters at the lowest price
