After googling, I got to know that ichimoku is basically a term for technical analysis but seriously you cannot analyze the price of BTC, if any crypto at all.

I would say the best way to earn is just to buy when the market is down and sell when it's high. It might sound boring, repeated and dull but really nothing better than this and the market is down right now, so you know what time it is. It's TIMEE to buy (in Bruce Buffer's voice, maybe?).
