it is so hard to be 100,000 in next 10 years but price will incrase more than 10,000 $ in future
about other altcoins yes bitcoin will destroy most of them
As we can see, most of them at the lower end of coinmarketcap are already dead and we may just only end up seeing few altcoins with great projects that will end up staying relevant at the end as long as they are able to convince investors of its maximal usage.
Bitcoin is going to stay on that top for now and obviously, we will just have to see how government regulations worldwide are going to have to play out. $100,000 is a possibility but when is what no one can really say for now.
