You can't fastmine almost 13 million coins in the first 2 years and not expect volatility and big bubbles to form. Monero is proving to be very volatile due to its mining emission curve and lack of masternodes.
Totally opposite. Monero was impossible to manipulate exactly because of higher emission in first 2 years. Manipulators got reckted by miners dumping their coins. That is why none pumpers group ever liked Monero.
High emission also keeps price of Monero low until now. So everyone had more then 2 years to buy cheap coins. Since coins are still cheap i can say 3 years, maybe even 4. But i doubt 5th year with daily reduced emission Monero will still be a cheap coin.
