Yeah, many people don't understand the right time for entry and exit. Some new people try to buy Bitcoin as much as possible in the current cycle, they don't know that it is bullrun season. If they know we will be heading bearish season, I think they will keep their money to buy at the next year. Many people still invest in random ways, they don't use the proper strategy yet. They too focus on the possible profits to reach.
Unless you are looking for a short term gain, there is always safe time to buy Bitcoin whether it's bull run or bear market. There is what is called dollar cost average, if you are willing to hold Bitcoin for long term, that's should be your best way of entry anytime you have money, you can and hold and at the end, the cumulative will give you an average buy price.
It's only people that want to buy when the price is low and sell when the price is high are chasing bull run and bear market up and down, the aprocach is good but the best is DCA because you will always be there in the market anytime.
