WHAT IS CRYPTOCURRENCY
what you need to know first is that cryptocurrency, like bitcoin, is a digital asset that has a value used for exchanges. Think about the days in past where there was no money, people used to trade in gold, than money came out in papers and in metal coins, this coins and papers' value depends on the economic situation of the country which means prices could go up and down. the same thing with cryptocurrency, a digital coin's price is tied to the number of exchanges made on that digital coin, for example bitcoin was in the beginning only costs 0.1 USD to buy, now it costs 8000 USD.
WHY EVERY ONE IS FIGHTING AGAINST CRYPTOCURRENCY
when someone wants to buy a car or house he pays through a bank check or bank transfer, in France for instance you are not allowed to pay for something in cash more than 3000 EUR. Even when you pay for something through a bank check or bank transfer, the government knows where the money went and what you have bought and knows how much money do you have in your bank account. Unlike other currencies, digital currencies can NOT be traced, no one ever knows how much you have or how much you spent or any thing else.
WHAT IS POSITIVE AND NEGATIVE ABOUT DIGITAL CURRENCY
Digital currencies costs almost nothing to transfer, and the transformation is fast. digital currencies are also a good investment, a digital currency could start with a price of 0.01 USD and within a year goes up to 10000 USD.
digital currencies are stored in digital wallets, wallets that are secured highly but still get hacked sometimes, this why digital currencies make a good target for robbers.
