I do not think that bitcoin will be enough if the whole people around the world will going to buy bitcoins. There will be too much shortage on bitcoin supply and this will lead also to have an expensive market price for bitcoin. As we all know that there are billions of people around the world and bitcoin supply is only limited. So meaning to say in the near future there will be a shortage for bitcoin supply and thus will lead to create another dominant coin like having ether as one of the possibilities that it will be the next to bitcoin. As of this moment i am seeing this already closely to happen. What do you think?
Whether there is a shortage or not, it will still be a good thing. As we all know, we make the market possible and shortage means less supply and higher value. To be specific, this is the law of demand and supply, when there is scarcity in the sources or the demands, prices are high, like for an example gold. Even if this happens, it only goes to show that crypto currency is growing and that the market can potentially grow and increase in the future.
