Cryptocurrency is one of the contributing factors to the improved economic status of Japan and South Korea. Blockchain and cryptocurrency create job opportunities like cryptocurrency merchants, project developing, bounty managing and hunting etc to the people and also offer financial freedom.
I believe the same. If cryptocurrency had been a scam or a bubble, it would not have been adapted and recognized by countries like the US, Canada and many European countries. In addition, I think it can save the loss of the values that otherwise would be lost upon a financial crisis. So in other words, it is saving value and prevents the rise of economic problems.
