Bitcoin seems to be the past and Ethereum the future.
The question is : when BTC will worth almost zero? Next year? In 2 years?

day to day the new new things ( irritating things) happens and this leads to make the ETC famous but soon ETH will ho down like ( may be ) . because the father of all the altcoins is bitcoin . so may be it can take some time to be more effective fir tge bitcoin .
