Printing crazy would make hyperinflation, which is worse that normal inflation. Though they still has to make cash out of thin air, since inflation is intended to be made. One theory suggests that inflation, while reducing the purchasing power, makes people actually use money, since they know that if they just hoard it, it would become less valuable and therefore, could only purchase fewer products.
If deflationary is used (such as Bitcoin), then there would be a tendency that when the prices got so high, people would not actually use the currency, but instead just hoard it, making it useless.
Hyperinflation was already experienced by Venezuela people. Taking its economy to a great depression. Printing of too much money is not good in economy. I thought before that it would help the people to solve from poverty but I don't that its counterpart that it will harm the economy as well. Deflation has its disadvantage also but unlike with other, bitcoin will become valuable and useful since many people are using it than hoarding or keeping on their wallet.
