Right now, price of ETH is low, is there again rise in the ETH ? I can see eth going above bitcoin because of combination between drop in the price of bitcoin and increase in the price of eth.
Yes, maybe, especially when bitcoin is too old. At present, ether can do everything that bitcoin can do, in addition to the low cost to a much faster transaction speed. Ether also brings more advanced technology, and has been implemented in various projects outside the ether, and this cannot be done by bitcoin.
