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. Bitcoin is a volatile, unpredictable asset. With the short-term thinking of trying to time your buys to the market, you're never going to get anywhere. There's no free money to be made. If you're serious about bitcoin, consider educating yourself and look into a more forward-thinking strategy like DCA. If you're just trying to make a quick buck, get out of here. Bitcoin is not for you.
Each day the trading session is divided into the time sessions of various countries like starting with Japan China European US and so on and henceforth. An app based website called Velo depicts these time zones clearly and trading volumes across various platforms. I/O indicators, Volume curve metrics and Calls and puts across various exchanges Deribit tells a lot about the direction of the movement of bitcoin asset. Social media signals sometimes help to trade this asset class as well but that is highly detrimental in the long term perspective.
This is not financial advice.
I'm not really sure if you are promoting that app or you are simply using it. In any case, it's just easy to look at the different timezones as there are a lot of websites that will do the conversion for you.
As far as timing the market, you are right, although there are what we call TA who do that for a living. They base everything on what they see and what algo they are going to used or using to "predict" where the market is going and then put money on that. That's why trading is being compared to gambling because of this unknown factors. Nevertheless, still up to us traders on what we know and what works for us.
And for the majority, this is like a stable job for them. Not saying that they are experts, but for them, thru years of experience, they could have anticipated and so they are going to trade and make money.
