The price of Monero rose more than 120% in the last few days. It is a good coin with anonymity, It might replace bitcoin.
I highly doubt that. We see huge spikes and falls on daily basis on many alt coins, and this 120% rise in price would probably be another pump and dump attempt.
I too dont think this would be possible. Currently bitcoin is the strongest cryptocurrency and it will continue to be the number one crypto currency. It was the first of its kind to take off and hasnt failed once since its release!
