You will be aware of the status of Bitcoin investment until you get involved in investing. The more bitcoins you invest, the less aggressive you will become, because investing aggressively will never yield good results. So Bitcoin is the only trusted coin where investing can get the most benefit, it needs a long time. If you invest in a long-term process and use the DCA method, you are most likely to have success. So it must be trusted to create itself, and it is the only bitcoin where the world's largest institutions and countries have invested in bitcoin.
The investment class with Bitcoin is a very large class because currently everyone who has known Bitcoin has certainly seen how world figures who are already rich enough still invest in Bitcoin until now. Likewise with other large companies and several countries that have also begun to believe enough in Bitcoin investment so that this has added more confidence in the minds of many people that Bitcoin is not something that needs to be doubted for its investment. As for the method of collecting Bitcoin itself, I think everyone will continue to do what they do most often and it still feels comfortable enough to continue doing as in the example of the DCA method that you said.
