You dont need to raise the price because it is not everything about the price. It is more about mass adoption because if you think that if the price raise than it will raise the adoption then you are wrong because the price raising will not attract people for adoption, it will attract more traders to dump it for profit
not really, it will surely attract new fishes that want to join the wave(the same thing happened with the 1200peak otherwise one could not explain why many bought at 1200...), also attracting more traders mean that they will buy and thus raising again the price
raising the price mean high demand, high demand mean better adoption
