So what do you think would happen if another Cryptocurrency (Example Monero / Ethereum etc) were to take Bitcoins spot as first in market cap?
Then there would be a new "KING" if that thing do happen on seeing bitcoin is being overtaken by other altcoins in the market.It would surely be a record and lots of people would be shocked specially to those who hardly believe on bitcoin but we do all know this thing is really hard to achieve,its possible but would really takes time and consideration on the community on switching out into a new coin rather than on bitcoin itself.
So lets say theoretically , People saw Bitcoin and saw its many problems involving scalability etc , and dumped all of their BTC for whatever crypto... Say they took the entire market cap of BTC into ETH or XMR...
Wouldn't it be time for people to say goodbye to BTC and accept a new King?
Now, I do not think there is any altcoin that can replace the bitcoin's position in the cryptocurrency market. Bitcoin always has a tremendous support community and its value, although volatile but stable, is the basis for evaluating other crypto coin. I believe in the next few years the value that bitcoin will have is huge because of its rarity.
