You should never think about ten years ago because at that time, risk could only bring success,
This makes little sense. 10 years ago there were similar kinds of concerns as there are now, yet we can see after the fact that investing into bitcoin ended up paying off quite well including that the more aggressively anyone invested into bitcoin (without overdoing it) then the better the payoff.
Personally, I think that similar kinds of underlying principles continue to exist in regards to the more aggressive anyone invest into bitcoin (without over doing it) the likely better will be the future payoffs, 4-10 years or longer down the road.
It is also likely the slope of the upward curve is not going to be as steep into the next 10 years as it had been in the past 10 years, yet these days, the downside risk of the next 10 years seems to be less extreme, too. When governments and large financial institutions are jumping onboard, it becomes harder to reverse courses... .not impossible to reverse but there is a certain value in the Lindy Effects that are created with bitcoin being in existence longer and seeming to ongoingly becoming stronger and stronger and stronger.
We do not have much idea about the next 10 years, but there is only one assumption that Bitcoin is more likely to go up in the future. Even this assumption is reasonable. Because in recent times, governments of different countries and big companies are expressing interest in Bitcoin investment, which is certainly positive for Bitcoin and strengthens its foundation. Since Bitcoin's price depends on demand, we are seeing the demand for Bitcoin increasing day by day. You may be able to predict the future of Bitcoin by depending on the demand of governments and big companies of different countries.
It is not possible to predict the future ten years using the past ten years as a standard. However, Bitcoin's strong foundation has started from the past ten years. At that time, being successful in Bitcoin was not risk-free, rather, I think Bitcoin investment was more risky at that time. Now we can reduce the risk of Bitcoin investment by gaining knowledge about Bitcoin and adopting strategies. We are even seeing a steady increase in demand for Bitcoin. Therefore, it is now a little easier to succeed in Bitcoin than it was before.
You are right that the more aggressive you are in investing within your means, the more likely you are to make a profit. Because Bitcoin is rising day by day, we may never get the opportunity to buy at such a low price again. You will even move faster in achieving your goal. Buy as much as possible at a low price and keep profiting yourself.
