In not all cases, you have to wait for the price of Bitcoin or other cryptocurrencies to fall deeply. You should have a bracket of how many percent you will buy a coin that you believe will give you good savings in the future.
There are many people who are confused by such a system; what they think is going to drop a lot in the market is suddenly just a fake dump, and if they continue with the baiting tendency, the fund will be stuck and the expected will not happen, unless you really have a deep understanding of trading here in the crypto space.
Shrink the scope and focus only on bitcoin. You won't get caught with fake pumps and dumps, even if you get a dump at some point you can still buy and accumulate them. The price of bitcoin will increase over time, even someone who is stuck at the previous ATH can still hope to get a return when the season bullish occurs. If you buy and continue to accumulate, your average price will get lower and will no longer keep you stuck at ATH, for example.
You can easily find examples like what I mean, so of course you won't be trapped in bitcoin if you have good financial strength. Even if you can still hold longer and wait out the bull run market for some time if you are stuck at ATH, you will likely find your investment in bitcoin to be profitable.
