Assuming the Citizens are all told to invest in Bitcoin in the current price and 3 years later, bitcoin price is the same or down like $10K, would you still say the investment has built the country's economy?
Investment should be a choice, and I think adoption and investment differ a bit.
then I want to know the difference between adoption and investment?
Yes, indeed, if Bitcoin goes down, of course, if you can't hold it firmly, the conclusion will be a loss.
but as I said, bitcoin investment is made as a side business, not the main business, because if it is made the main business, of course we are afraid that the price will not match what we expect.
