No Inflation
One of the lingering financial problems affecting the world is inflation. The value of nearly every currencies around the world decreases by at least a percent or two every single year. The reason is because governments print more money than they take out of the system causing the value to go down.
Well, this problem is guaranteed not to occur with cryptocurrencies. Sure, the value might fluctuate, but this isn’t because of excess money printing. They each have been made to have a finite amount. In the case of Bitcoin, there will never be more than 21 million. No extra Bitcoins, no inflation.
They are Global
When you travel you have to convert your local currency to the currency of the place you are going and when you do, it costs you. Then when you come back home, you have to do the same thing and pay again. Also some countries have very unstable currencies and if you own them and the currency collapses, you lose everything. Cryptocurrencies are global. They never have to be exchanged and if a country collapses, you still own your cash.
Almost Untraceable Transactions
It is true that today Bitcoin and some other cryptocurrencies are being used for illegal activities and this points to the need for regulation, but the nature of cryptocurrencies is that they shield the user from detection. As regulations come in, this might change some.
There are other benefits that will come about when things settle down a little bit like ease of use and that it is an appreciating asset. Cryptocurrencies are the future.
