every investment has a risk, so does investment in cryptocurrency. the difference is only the percentage of risk, if the results obtained are more and more then the risk received is also greater.
But we should also think about the direction of average growth in the crypto. We see loss and rise in the worth of different coins in the crypto market but the average rise in the value of a coin like Bitcoin is always more than the fall so we are actually rising but with low pace.
Having said that, investing in crypto is an incentive for quick and often easy earning and it can improve the economy in a country. The only clash will be that between the fiat system and the crypto because of the fact that many policies and the financial institutions are build around the fiat system.
