Of course, I'm new to this topic, but it seems to me that if we consider bitcoin as an investment in the long term, then the purchase may be justified, even if the price is high now. But in order not to incur losses, portfolio diversification is important in any case.
Portfolio diversification is important when investing, but if you only invest in Bitcoin, I think you only need to focus on buying it repeatedly when you can afford it with a certain amount of money. Because everyone does not need to be afraid to invest in Bitcoin in the long term, especially since the evidence is also quite clear that investing in Bitcoin for the long term can bring more profit than the level of loss that Bitcoin holders are more afraid of. Now you can see for yourself how the Bitcoin price pattern has been since it was first marketed until now and you can also imagine how much profit has been obtained by most people who have invested at that time until now.
