Is Ethernum a threat to Bitcoin?
-Ethernum is faster than bitcoin
-has been gaining popularity
-its good for smart contracts.
Is Ethernum going to replace bitcoin, die out as a fad or coincide with bitcoin? Are we likely to see any altcoin possibly kill bitcoins or will bitcoin simply incorporate any improvements from altcoins, taking away all advantages.
There is a low probability that bitcoin will be replaced even 20 years from now
Ethereum on the other hand will increase in price but it can never replace bitcoin. It's like pounds to dollars, pounds has a larger value compared to dollars but did not replace dollars. Ethereum may one day has a larger price compared to bitcoin but will not replace bitcoin.
