Stop trying to time the markets. We don't know if it's going to go up or down. If someone says they know, they're lying. If they knew, they'd be making a lot of money with it, they wouldn't be trying to convince you that they know.
No body has the full prediction on what the market is going to be like and still be accurate about it, we all are trying our best to ensure that there's nothing missing about from the market as we speculate it performance, we can use any indication in knowing what time of the market are we before timing but for our own personal interest as we invest, everything we speculate of should be on the bid to maximize our potential for making profits in it.
While no one can accurately predict the market with 100% certainty, there are certain indications that can help gauge whether you should purchase crypto at given period or not. There are factors that must be consider that can support your decision in order to at least give you an idea the best timing to start purchasing BTCs for either short or long-term investment.
I agree with what OP has mentioned- no one has the capacity to know the market fully. If someone claims that they can "break" the market and they will guarantee your richness, then respectfully walk away because it is most likely a scam.
There are some persons that time the trading market by predicting the movement, once they notice a particular pattern the market is trending towards, they will quickly say it will remain down or it will rise. So people do make predictions, but it's also advised for you not to rely only on what some other persons have predicted, it is also good for you to do your own findings and map out a pattern that will work out for you. Before you start trading the Bitcoin market, you have to first educate yourself on how the market is traded.
Like what I also mentioned, certain factors indicate predictions on the movement of its price. While it is not 100% guaranteed, the patterns can help you decide whether it would be the BEST timing to purchase cryptocurrencies or not.
