Yes, I think that Bitcoin is in a deep stage right now.
In 2025 Bitcoin is no longer a hidden gem so it is not in a deep stage now. You can say about it in 2009 or a few years after that and get aggrement of many people as Bitcoin is a hidden gem, but if you say it in 2025, I am sure most people disagree with you.
Because the way Bitcoin's value has started to increase and its popularity is spreading, even if its price fluctuates in the future, it cannot be expected to be much lower than the value it currently has. If anyone can invest in Bitcoin on a regular basis using the DCA method, can definitely make good and unimaginable profits.To get actual profits from Bitcoin must invest for a long time. Because investing for 1-2 years doesn't really have much impact on Bitcoin's valuation. Need to invest for at least 4 to 10 years.
