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.
Same way most people who recently began investing are wishing they started 10 years ago is the same way people who are still procrastinating now would wish they started earlier too in 10 years upwards, if you take a look at the figures you'll see that it's still earliy compared to what we all hope it would be like in the next time years, if they picture bitcoin at $1m or above in 10 years from now then the investor who started recently would stop wishing they invested in the past but take their current investment seriously.
You'll hear people say it's not too late and they're right afterall cause if one could start now an hold till 10 years time when bitcoin probably gets past $1m then they won't even feel they missed the opportunity earlier investors of about 2011 to 2020 had cause they too would've made lots of profits in 10 years from now whether they're very aggressive with their investment or not.
