As long the demand of cryptocurrencies is about to go up and the supply is settled, theres huge potential. Until now it did. Think about it. Even if people do not invest in Bitcoin. Can u imagine that people will pay with a currency that is mathematically safer, cheaper and faster ? In other words, maybe it won't be Bitcoin with what people are ging to pay but at the end of the day, the blockchain system is more made of serving peoples needs than the currency system today. Or what do u think ?
