What you suspect is true because no one can make predictions for the future, what we have is faith and historical evidence. It is often said that if you want to predict the future, you need to look at history because at some point everything will always repeat itself. I also hope history repeats itself but if it doesn't then I don't worry because just looking at the development of bitcoin we can rest assured that the future of bitcoin is very bright. It's only been 14 years but look, from something scorned and despised, bitcoin is now being accepted on a national level. That growth alone is enough to believe that its future is bright whether we have a halving event or not.
Bitcoin has always bounced back in price, even when it has gone through the worst. I'm pretty confident the same will happen again after the next block reward halving. Those who didn't buy BTC when it was trading below $20k, will regret themselves when BTC gets past $100k per coin. After the pioneer cryptocurrency reaches a new All-time-high in price, it's very unlikely it'll be worth less than $20k again. That's why it's important to take advantage of every dip in price to help secure your financial future.
Who knows if buying BTC now will make you extremely wealthy in the long term? As long as you don't invest more than what you can't afford to lose, you'll have nothing to worry about. Just my thoughts
The fact is that no one is able to predict the future with any certainty, but I also believe that bitcoin will recover and be able to reach its ATH within the next halving. I also believe 20k or under 20k maybe this is the last we will see it, like 3k happened during bear season in 2018, a lot of people regretted not buying bitcoin at that time and now history is repeating itself. We cannot say that holding bitcoins will make us rich but we will certainly have a better life if we invest in bitcoin.
