Small business normally don't make it past 5 years because they can't compete against local established corporations. Even if everyone buys local they would still not survive.
Corporations are so massive that they can lower their price, undercut local business and wait several years of not making any profits until the local business goes bankrupt. That's their strategy and it works well because they are global and have global profits.
It would only make sense to open a business with your Bitcoin profits when Bitcoin is not producing as much profits anymore. We are not there yet. Bitcoin is still producing a lot of profits.
As the world keeps savings in Bitcoin and dealing with Bitcoin corporations will start to go bankrupt as well. We are seeing corporations go bankrupt recently.
There will be a time when Bitcoiners will have to start opening up businesses with their profits as making money will be much easier but real estate has to fall hard before I would suggest you even open a business.
It's much better to work for someone and keep saving in Bitcoin. Let the business owner deal with the stress and headaches. Things will continue to get worse and more business will fail.
Almost everything is produced in China. You can skip the middle man and buy directly from China. I have used AliExpress for years and it has saved me thousands and thousands of dollars. Quality is the same even if you buy local because they get it from china too.
If you are in the USA it might be different but in Canada local business don't produce their products locally. We are an unproductive nation.
Buying local just makes you more poor.
I am the business owner. I am the productive class.
