Cryptocurrency gives me freedom of earn and no third party involved here. If i invest flat money there are many restrictions by government and money londering situations if i transaction lots of money. There crypto currency gives me free fair involvement. So i love it from my best.
besides cryptocurrency provides freedom, another thing is cryptocurrency provides a lot of benefits in trading and providing profits. so that's our main reason for needing cryptocurrency.
The main purpose of crypto currencies is that they are decentralized in nature. No one control them, bitcoin has limited supply so there is no inflation. The value of bitcoin will not decrease over the period of time in the long run.
