Are we in Bull or Bear Market?

When is the bullrun starting? i kept hearing alt season, meme season and all sort of season. how do i know when the bullrun start or has it really started? i saw a post on x this morning that “the four years cycle has ended” and i wonder if we are now in bear market. wait do i even understand this terms? Which token is best to hold during this season because currently i have bgb, sol, ada, xrp, and few btc in my wallet. is there anything i need to know about this bullrun or bear market?
