What do you think? Is the gap too big between Bitcoin and others? Could Ethereum or any other currency get a huge raise and topple Bitcoin?
My opinion is that with a good real-world usage application, one or many of the new coins could gain greater value than Bitcoin in a year or two.
Yes.why not? If bitcoin can then why other cryotocurrency can't.
The first cryotocurrency invented is not enough to stay forever in the top,it needs to be really better than other currency if it want to stay at the top.
For example Google is the best search engine on internet for now,but it is not the first search engine invented.So which one is best then it will go to top.
