1. Increase economic income by cryptocurrency?
The effect of some cryptocurrency is terrible for the economy, especially currencies that have no value or have no specific goal.
If we need cryptos, creating more than 1,000 coins/tokens is useless. I believe that 99% of cryptocurrencies are zero.
Some cryptos worth $ 0.0005 and then tapped to $ 1 and others in the process of creating money from scratch, so if any regulation/collapse happen, most of these currencies will return to zero.
2. The Cryptocurrency Market and How it Influences Our Economy?
The effect is currently limited to individuals so you do not invest what you cant lose.
