In order to invest in bitcoins, you need to buy bitcoins at a time when you will not lose money in the future. Bitcoin market changes every moment so invest by understanding the market position. There comes a time when the Bitcoin market turns into an absolute bear market when there is a golden opportunity to buy Bitcoin. At this time buying Bitcoin and holding it for long term will definitely lead to success. But there are some times when the bitcoin market is bullish there are many people who invest but they don't get that much profit. But if you want to invest in Bitcoin, you must invest when the price of Bitcoin is in a bear market. And selling when the price of Bitcoin turns into a bull market can lead to good profits.
I feel like it doesn't matter when you first buy bitcoin, even if it was 69k that is fine, obviously it would be better if you buy at the bottom but just because you bought at the top doesn't mean you need to lose money. The only thing that matters is the fact that if you end up putting in more money.
That means if you bought at 69k, but then kept on buying a lot more, and even bought a lot at under 20k, maybe your DCA is about 30k right now? And that means you could get close to profiting these days. That's what could be a good way and I have done something similar, didn't buy at 69k but bought at 42k and I am in profit right now, why? Because I managed to buy a lot more when it dropped, a lot more at under 20k as well, and that helped me.
