The earlier the better since it will bare more good result if they invest at earliest age.
But that depends on what age they know Bitcoin since not everyone is lucky to know this coin so early.
Still they can do good decision by investing on Bitcoin right away then do HODL with it. Somehow they can decide to do 5,10 years or maybe longer than that especially if they are young.
If they are at 70's still they can buy Bitcoin and for inheritance purposes. Nothing stop people to do it since it can give good fortune to their recipients. This is how cool Bitcoin is since its flexible and we can use it on whatever purpose we are aiming for investing on this coin.
In general, whether it's starting a business or starting an investment portfolio - the earlie is ALWAYS better, and it's not my mere opinion. It's a FACT.
Plus it's not only because of the possibility of gaining more profit. It's also because starting early also makes you LEARN early, or make mistakes early so you could learn from them. Making a massive investment error in your 50s is more dangerous for your financial health than if you made it in your 20s.
. I never had the right information such as investing in Bitcoin mainly and followed in searching for the next Bitcoin when I started, invested in a couple of shitcoins and lost heavily in the process, an experience I look back to and still regret till date. Like you said, it is better to make mistakes early and learn from it early, and that is my case although I learnt at a huge cost.
Console yourself? No ser. You should be happy that it happened. Sometimes learning the HARD WAY makes the process of discovering the right path faster than merely learning the lesson from others. The experience itself is more valuable.
My joy is that I'm doing the right thing now, investing mainly in Bitcoin and holding with no intention of selling even in this market cycle and the next. I have not reach my accumulation goal so I'm still aggressively investing my discretionary income until I meet the target I set for myself in terms of Bitcoin quantity.
Although, if you let me give you some advice. - Be careful about "targets". Don't make them the actual goal, but use them as a sort of guide because you may want to add more Bitcoin that's more than your original "target".
Let it not be that there's timing limit here. It's also no one's fault who've to invest in bitcoin lately. It all depends when they learnt it, build their emotions towards the market fluctuates with the rest of the investment risks. I either don't expect anyone at their retirement ages such as 70s to be the beginning of their Investing on bitcoin because bitcoin profitablity doesn't come so soon and the old folk needed to enjoy the ride watching the the market behaving dramatic and same time keeping those smiles as he sees his portfolio growing when the market soars.
All of this maybe challenging for one to invest on bitcoin at that old age but yes, you don't have to end up spending all of your savings before you exit the earth so, necessity to invest even at that old age can still be considered for generational inheritance as part of your portfolios.
I agree with the saying that earlier is always the best but bitcoin being a newly technology and one investment scheme is what we don't have to regret our actions of late coming.
Buying and buying more and just hodl can always take us to that dream of owning a huge portfolio even when we came later.
The point I'm actually making is not how early or how late an individual starts his/her Bitcoin journey. It's merely knowing the pros and cons/advantages and disadvantages in doing something depending on the individual's age. This is only a fact of life.
Older people in the 60 to 70 years old age demographic probably also had a Golden Opportunity to invest in something during their 20s, no?
