Monero of course will rise 100x-1000x. A mass used cryptocurrency should and must first of all be anonymous. Otherwise it is a state, corporate or small group of people scam or market/people control technique.
It would surpass BTC if so, I doubt it
True, monero is a solid coin and it is a good investment for anyone interested in crypto but monero has some issues the most important is that it does not scale, if you think bitcoin has scaling problems then monero makes bitcoin look like a spaceship against a car, monero is a niche coin only for those that their primary focus is on anonymity.
