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.
Regarding what Popkon6 said, even till now risk also bring success but not all risk though, investing with what we can afford to let go is also a risk maybe someone people don't know about this but it is true and if you are doing it consistently for a stipulated time, it will surely payoff just like it has..., aggressive Investment is advisable as long you have the capacity.
One thing that gives me joy the most is seeing great nations and great institutions investing in Bitcoin, this alone speak good about Bitcoin and i believe the reason for this act was because of the potential of Bitcoin and they have the feeling It will do greater in years coming and I can feel and sense it too. Anyone who has all it takes to start up after seeing this happening and refused to invest is really making a big mistake even though the person has other investment and the sweetest part is that you don't have to invest at once, you can invest gradually regardless of the amount and the market price using the DCA and success can still be obtainable if carried out properly.
