This is the future of the world now and we became a part of it. There may be setbacks but there will always be the good old Bitcoin that will be left and those who trusted in it will feel how blessed they are for standing beside it and just keeping their coins.
About Lessons. I do believe we must try to filter it out more on whatever we will trust. Try to also listen to the speculations and predictions of other people/traders/investors and not just the advertisements using the popular names in the world. FTX is a good example of that. I am glad I never became a part of it. Those who have experienced Mt.Gox may have known about what is coming and they may also be the ones who avoided this regretful event.
Nothing that is great in this world has come without any cost. We had thousands and thousands of years of human lives, and mostly the last 5 thousand years is recorded somewhat, not perfectly but give or take, and the last thousand years is a bit better recorded.
Look at all the good things that happened and tell me one that just fall on anyone's lap, almost all the things that is good in this world came after hard work and pain, and that means bitcoin will have hard periods here and there, but it will end up being the best currency in the world. It is already the best currency to me, but not to many parts of the world, and they will agree to that when the time comes.
All technologies present a challenge to the generation that first implement them, when automobiles were first created cities as we know them did not exist, and the same can be said about many other inventions like the electricity or the internet, they have changed the way people live their lives in a radical way.
And bitcoin has the same kind of potential, it just that the fiat system has been in place for decades already that people forgot that the economy has worked with a hard form of money for the majority of our history, and it will require that we change the way we think about money before bitcoin gains the level of adoption we are looking for.
