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?
With respect to my own feeling in regards to this issue I do imagine that in the coming more years as the BTC people group is continue developing this issue may have a high probability to happen to have a lack in BTC. Well I figure this is something to be thankful for to happen and ideally the BTC will thought about it as a chance.
