You've hit the nail on the head when you say that one of the most crucial elements in investing in Bitcoin is time. Your chances of getting a good return on your investment increase with the length of time you can hang onto your Bitcoin. Similar to a snowball effect, your investment will increase over time. Additionally, as you mentioned, you'll gain more knowledge on how to maximize your investment over time. The misconception that most people have when investing in Bitcoin is that it's a get-rich-quick scheme, but that's clearly not the case and that if they just start investing in Bitcoin, they'd be rich in a month or two, and this infact is the actual reason why most Bitcoin investors go into the short-term trade and they end up loosing money and giving Bitcoin a bad name, they go all in without really having the knowledge of what they are doing and then at the end incur losses for themselves. Bitcoin is more of a long-term game, and if you really wanna rip the true benefit of Bitcoin, then going long-term will definitely help you achieve that.

So yeah.. 4-10 years or longer would be a good way to think about any bitcoin that you buy to have at least that kind of timeline, so if you are DCAing into bitcoin for 6 years straight, then your earliest BTC buys would have had reached investment timelines of 4-10 years or longer,
