So what do you think would happen if another Cryptocurrency (Example Monero / Ethereum etc) were to take Bitcoins spot as first in market cap?
Well, the worst case scenarios will be the death of All high gainers who got the most share of it, but i do not think this is going to happen ever, currently BTC is touching 60% of Market dominance which is very rare after the surge of crypto currencies, Even ETH is taking sell load so i am very optimistic that BTC is not going anywhere.
