Digital money, a good option to invest?

Lately the ways of paying have changed. The most common way of paying is cash, which is mainly used by elderly people and for small purchases. Cash contains coins and bank notes which change depending on the country. For example, in Spain and the European Union they use the euro, in the UK they use the pound and in Russia they use the Russian ruble.

Nowadays there are more ways to pay. You can use a credit card, which is very useful when you are paying a big purchase and you don't have enough cash. You can also pay by PayPal when you are doing an online purchase. Recently we can also pay something with our mobile phones with an app and you can use it as a credit card.

Recently we can see a new way of paying: bitcoins. These coins are digital coins that you buy with real money and whose value goes up and down. You can buy things with these coins, but the main purpose of people who buy these coins is wait for the price to go up and down and sell them to earn money.

In my opinion, money is evolving with technology and we have to adapt to the new ways of paying. I think these ways of paying will evolve and in the future cash will dusappear. I also think that bitcoins are a good option for those people who know when to sell them because if you don't sell them for a higher prize, you will lose a lot of money
