Unfortunately, a similar situation already happened in 2017. A lot of people got burned about bitcoin while investing in cryptocurrency in 2017 - early 2018. I don’t think that the situation will happen again, people perfectly understand the instability of bitcoin and the crypto market, they will be careful to carry money into this area. Probably before halving we will see a few drawdowns of bitcoin, perhaps until the beginning of the year, maybe there will be more panic sales, after which the price will go up to the levels of 15k - 20k +.
There's a strong chance that the market will begin to show another run after this year, news about halving most of the time creates a good sign for investors to place again there respective entries. those investors are carefully analyzing the situations they've learned from previous mistakes and won't like to experienced same thing again.
Same with what you said, investors are wisely nowadays. Will wait for new good news and observe if what will be the reactions coming from the majorities before taking any actions.
