Very nice purchase, it's a big purchase friend you invested in Bitcoin it's very desirable. But Op if you don't invest at once, it would be best to invest following DCA method. Investing in Bitcoin with the DCA method will make you want to invest more, and you will always want to invest in Bitcoin. It's good that you invested now because even though the price of Bitcoin is a bit bullish at the moment, and the price of Bitcoin will continue to improve even more in the future. So I never consider investing in Bitcoin as a risk, I think investing in Bitcoin is a good decision.
