Buying bitcoins little by little and withdrawing them to a personal wallet is the most effective way. I've been doing it for a few months and now I think I'm pretty successful even though I only have a few bitcoins at the moment. But I hesitate to buy again when the price of bitcoin becomes too expensive. Do you have an opinion? Unfortunately I just found out about this forum, if I knew about it a long time ago maybe I would have more bitcoins. Even though I've known about bitcoin for a long time, I was hesitant to start buying bitcoin for a long time before finally deciding to start buying it on binance
When Bitcoin prices become more expensive, you may stop for a moment to wait for a correction. You can buy it again when the Bitcoin price drops and accumulate it. That's what investors usually do.
However, when people use the DCA method, they may continue buying Bitcoin until they have decided to stop buying it. They just wait or continue buying Bitcoin, depending on their respective plans.
Many people feel it is too late to buy Bitcoin because some have known about it for a long time. But they just decided to invest the money in Bitcoin. So it all depends on each person's plan to continue buying Bitcoin or postpone it until the Bitcoin price declines or experiences a correction.
