one of the biggest problem with dollar is inflation.. over time all currencies lose purchasing power because government keep printing more money.. with bitcoin you don't have this problem because the system is designed to make bitcoins to be finite.. only about 21 million bitcoins will ever be released.. the release of new bitcoins is slowly down and it will stop completely within few decades..
No matter how much value fiat currencies are losing after years, people will continue to use it without thinking about the consequences.
These people are like sheeps. They do what their other fellow human being is doing.
bitcoin is not money, while the dollar is money.
Both have a different role and if I may say both have their world, respectively.
how is bitcoin not money. bitcoin can fuction as multi tool for plenty of things. it's a currency, it's a store of wealth, you can use it as an investment tool, you can store data on its block chain etc. i mostly use my smartphone in combination with my banking app to pay for my daily needs in store. i barely use physical money anymore. tell me how is that different from you using bitcoin as currency to pay for things in combination with for example your smartphone.
