I don't think Bitcoin was made only for countries with failing economies. In my own opinion, that kind of understanding is wrong. Because Bitcoin doesn't discriminate whether you're rich or poor, whether you have a job or not, as long as you decide to buy it, whether a small or large amount, you can own any amount of Bitcoin.
That's what's great about Bitcoin and what sets it far apart from other assets. With gold, can you buy $10 worth? With diamonds, can you buy that same amount? Same with silver, real estate, and others—right? You can't. Only with Bitcoin can we do that.
Bitcoin has not pointed out any comparison, so its actually created for both. But if we analyze it well, bitcoin is made to see such growth and progress. The failing economy will recover and prosper while the developed economy will take the lead towards a more developed and established economy.
Bitcoin is made equally for everyone. But those who first notice its potentials and take advantage on it first will definitely experience and reap their success while others have chose to delayed it because they doubted first the potentials of what bitcoin can do for them. Its like they need to see the results first before taking such risk with bitcoin.
