I agree with you, I also don't understand why so many people like to think about scenarios that are almost impossible to happen in the near future or within our generation. While many other people are spending their time accumulating bitcoins and they are making a lot of profit from it, we are spending our time doubting and worrying about meaningless things. It was really just a waste of our time.
It is the human nature to over think and make up scenarios in their mind and speculate on them. We should indeed focus on things in life and keep our mental trauma to a bare minimum. Bitcoin is just one part of our daily lives and collecting it should be our objective, it is not something to lose sleep over, after all its money in another form, you will not be taking it to the grave with you.
Bitcoin users should spend more time with friends and family, ease out their minds before coming back to crypto.
Bitcoin has and continues to become the world's trend and focus, so instead of continuing to doubt, we should take advantage of this unique opportunity to improve our lives. Doubt and worry never help us have a better life.
OP's questions were out of context, I hope they got what they wanted to know. Keeping your coins secure is important and no one can make bitcoin "lose" like that.
