Even if we do everything perfect, we are still not guaranteed to make profits - even though if we engage in strong cashflow management practices, then it becomes less likely that we are going to be easily shaken out of our investments based on sloppy practices.
No guarantee about future and existence of Bitcoin so no certain profit from our Bitcoin investment. There is always uncertainty in everything we do, including our investment, with probability of profit and loss. Good management is helpful for reducing risk while increasing chance of success but there is no management that can completely eliminate risk.
I understand that nothing is guaranteed but your stand on the future of Bitcoin is totally discouraging. If we don't have some level of faith in Bitcoin that it will give us good financial return in the future, how do you expect one to be committed to buying and holding? Some of us are not just following the crowd to buy but doing it dutifully as a retirement plan and part of what we will be handing over to heirs, with your position in Bitcoin, it brings some form of fear and skepticism. People who had this opinion a decade ago are today regretting why they never got started with Bitcoin the moment they knew about it; I'm sure 10 years from today some people including you will always regret why you did not take this seriously when others were taking the risk anyways. I will try my best not to allow this deter me because there is a saying that "no risk, no reward".
