Personally, I do not like ideas of "going all in" to investments...
To me, it sounds like gambling and or trading rather than investing.
Even though I get the idea that reserve funds can be saved up in order to have extra cash that goes beyond regular DCA buying to be able to inject into your BTC investment at various points along the way, especially at various dippening points.
You are right but investment is now the only way to be profitable for everyone, trading or gambling without experience is not very profitable, if one invests in Bitcoin now, it is almost certain that he will be in a profitable position within a few months.
Also as per your suggestion if one trades and gambles intelligently then more profit is possible, but most of the wise people can't do these things by following the right rules.
Yes, currently the Bitcoin market is down a lot. A few days ago, we saw that Bitcoin rose to around $49,000, but now the market has come down to $39,000. Those who are interested in investing in Bitcoin should invest in DCA method on regular weekly or monthly basis from now on.
Trading is all about luck, you must be a professional trader to make a profit from trading. The result of trading may be uncertain profit or loss. But if you invest, it is sure that you will get profit in the future.
Maybe many have sold because of the fall in bitcoin prices, I am still holding the investment and my goal is to hold until the end of 2025. I think the drop in bitcoin price means an opportunity to increase my investment volume. The lower the price of Bitcoin, the more I will invest.
