You need to look at price action, and specifically, Heikin Ashi candles along with the Volume Indicator to tell you whether it's okay to FOMO. Use lower time frames to get in quicker.
Mostly, I never recommend it, but sometimes where there is strong buying and a clear trend change, a dip might not come for a while. And when it does, because it went up so fast, it can usually lead to a downtrend so you have to be careful. Especially in crypto where there is Bull Trap manipulations upwards.
However, the Volume Indicator can tell you if the bears have lost, which on the left hand side, they clearly lost as we went from Green to red to immediately Green again, showing the strength of the Bulls.
