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.
I don't think so, both ethernum and bitcoin can go along together and remember, the price for each bitcoin is more expensive than Ethernum. If the bitcoin's price is very low, i think Ethernum can replaced bitcoin.
