I'm not sure about this. While I am a huge crypto enthusiast and I'm convinced that these types of currencies will be the future of money, I think that bitcoin is a bubble because people are not using it as money or as currency. Most of the newbies are entering the market just hoping to get higher returns on investments in fiat money. No one is buying cryptos like BTC, ETH or LTC because of them anymore. They are buying them in hopes of getting more dollars later.
