Ultimately it is good for each of us to get our priorities straight, including that a lot of people fail/refuse to invest, and maybe they do not have opportunities to invest, so they may end up working their whole lives without really being able to stop because they don't have enough money to be able to stop or even to slow down without suffering from their lack of any kind of meaningful nestegg.
Bitcoin provides an opportunity for anyone and everyone to invest, even with a relatively small amount, but like you suggest Sim_card, there should be some kind of a meaningful amount in order for the outcome to have some kind of potential for meaningfully impacting the person.
You are right because so many people failed to realize the importance of investing on Bitcoin instead they are more focus on working, although I'm not disputing the fact that work is not good but one thing they would need to realize is that there would come a time in there lives when they will no longer have the strength again to continue working and perhaps they will start finding it very difficult to cope including so many other needs that would pressing, so this is actually the right moment for people to set there things right in other for them to have a sustainable live. However is just like the conversation I had with a friend that normally work for one certain company, so he told me that considering the nature of the work and his age that it would be a very wise decision to start diversifying some of his funds to Bitcoin investment for holding so that when the time comes when he Will no longer have the strength or being retired from the work he would have something to rely on, and that's the truth because Bitcoin present a very huge opportunity for people to utilize and become sustainable in the future.
So far as life is concerned everyone needs to prepare their future on time and the best way is to learn a good investment practices that will stand as a relief at a time when we won't have the strength to work much again because that is what will smoothen our financial position in the near future and we should do away with the fear of failure and be very positive as well apply the best investment strategy that will enable us to become successful investors. Investments are attached with risks but the risks are minimal more especially when we invest in Bitcoin because you don't need to be disturbed about your investment as all you need do is just to keep your investment goals alive by accumulating more at every time there is a dip in the price of Bitcoin.
Having Bitcoin as a means of retirement is not that bad but just like your friend talked of diversification, it should not only be focused on Bitcoin investment alone as he can also venture into other forms of investment that will second his Bitcoin investment because despite that Bitcoin investment look somehow secured in the future but it is necessary to also get involved in other aspects of investment. My reason is that with the way Bitcoin is gaining more recognition and adoption, some may misinterpret it to a get rich quick project, not that it is not but it takes longer time which some persons may not really be able to endure and at the end may decide to withdraw their assets because in this modern or digitized world now, almost everyone wants something that they would start experiencing the impact at a very tender stage.
