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.
for now, bitcoin can not be replace in any of altcoin, maybe if there are no bitcoin again or the supply is end, then maybe bitcoin can be replace with another and it takes a long time before it will happen.
and for ethereum, there are posibility to be second bitcoin but not this time, it should wait until next years.
