Things like this are actually an easy situation, it's just that when what happens now with the attitude of most people who are lazy, this becomes a polemic even though when they are serious about something, especially for investment in bitcoin, they should realize that it must be done because after all, when you really want to be serious in bitcoin, learning and looking for all forms related to bitcoin so that we are not misguided is actually the basic thing that must be done first so that we know that in the end not only good things exist in bitcoin but there are risks that we must realize from the start.

So that when we understand more about how bitcoin works and how we should respond to bitcoin then at least we know what plans to do but this actually looks like it is difficult to do because we are too lazy in looking for something because our mentality just wants to be fed without wanting to look for yourself.

Since it is known that Bitcoin has a high return in the long term, it may be said that it will be less risky if you keep your investment for a longer time. Of course, so far Bitcoin has always provided returns in the long term, but there is always risk. There is no guarantee that what happened before will happen again. This is exactly where risk comes into play, and the investor, who knows that Bitcoin has always provided returns in the long term, invests by taking risks.

Sometimes it is necessary to consider investments independently of risk. Watching Bitcoin spread and following the stages it goes through can also be a valid reason to invest.

Lots of people actually heard about bitcoin in the early days but were reluctant about it or rather they were too scared to invest in it. In my country it was around that period that a ponzi scam happened and it scammed a whole lot of people and this was an online platform called MMM, it was like an investment opportunity that ask people to invest money and make profit after a few weeks without really doing anything. People were ignorant about ponzi scam then and some people started investing and cash out a reasonable amount which then draw more people in it by believing it’s not a scam platform.  That was how lot of people got scammed after they have invested their money.

This was one of the biggest scam that happened then and it affected a lot of people in the country so ever since people find it difficult to trust any online investment platform. It was the reason why lots of people were reluctant about bitcoin when they first heard of it back in the days. It happened to me as well, my bitcoin journey would have been different if i had invested when i first heard of it or if i had made research about it then.

The most interesting part about bitcoin is that it’s never too late to invest in it and you can always invest anytime you like just that investing early would make you more profit since you will have the chance to invest when the price is lower.

This is an eternally true adage in the field of business because if a businessman does not take ricks in the business he will never be able to profit from the business. This adage is equally important when it comes to Bitcoin investing. If one can invest in Bitcoin and hold it for a long time then that investor will definitely have a chance to get a big digit profit from that Bitcoin investment one day. Every business has risks and only those who have the will power to face those risks can profit from the business.

Too much enjoyment of life makes it happen so that we are too complacent with what we have now so that we forget the conditions for the future that we should think about because we will definitely have some conditions where the wheels of life are spinning so that even if we are currently at the top but it could be that on the one hand we will be in a slightly worse economic life and that's what we should anticipate from the start. The problem is that sometimes we are too comfortable with the current situation which makes laziness even greater.

The fact is as you say that in the end sacrifice and hard work are the determinants so that we get better in the future, it's just that things like this sometimes with too comfortable our conditions actually make the situation more complicated because we are like complacent and don't want to think about the future that hasn't happened yet even though it is an important first step to make us successful in the future.

This incident would've happened in most people's lives. Everyone sees it differently when they hear about it for the first time. With time, they'll start understanding the better part of bitcoin. OP seems wise, requesting his brother to try it first and understand the reality of the market. He had thought to be on the safer side, but he lost the opportunity. If he had entered the market earlier, he could've known better and taken the risk.

Even now, if we go explain it to a person who isn't aware of bitcoin, they'll say, Wow, $70k for a single coin. Thats it, and further, their minds never think of it as a better choice for the future. Later in the year, these people realize that we had an opportunity to make good money and have missed it. The best part is that it is possible to invest based on our abilities, as it has multiple denominations. So, entering the market at the earliest increases the chance of making life better  

       Buying or seeking to own bitcoin is a matter of choice, as most people know. And Bitcoin belongs to the category of investment in terms of long-term. Moreover, it is proven and tested because most institutional investors are obsessed with investing and accumulating it as their additional assets in the long term. 

      If these big businessmen already have an interest in Bitcoin, how can a person like me who has an interest in Bitcoin also save like them and even in other cryptocurrencies that also have the potential to give me earnings in the future?

The point is that there must be a business and also a willingness to build a business through courage in taking or facing risks, because this does not only apply to Bitcoin. But this also applies to many businesses because each business has different risks and the owner himself must have the courage to face any risks if he wants to achieve greater profits in the future. Things like that cannot be denied because there are no lazy people or afraid people who can get more profits through anything, because the term luck also doesn't often come to people who just sit still without doing anything or investing anything in their lives.

Measurable risks will maximize the profits obtained. Indeed, the greater the risk, the greater the results obtained, however, with good knowledge we can minimize the risks that occur, that way we have a good strategy to carry it out. Many people are only speculative, and hope for luck in their lives, and when something bad happens, such people will not be ready to face it.

You are right, there is truth in your words. I want to add that every novice trader believes that there is some kind of secret tactic for trading Bitcoin, but in fact there are only three trading styles:
waiting for the price of the cryptocurrency to fall,
waiting for the growth of the cryptocurrency,
trading in the price corridor.

And each of these strategies goes against the others.
And the worst thing is to start trading on one, and then switch to another. But often many do.
