It is what the app can offer. The price can go much higher according to the business model and what it has to offer. This is the reason behind such rise, MCO and TKN are the only ones bridging the FIAT-ALTS gap with MCO the closest. We all have lots of digital currencies and we all need to use them in the real world. The "correction" to happen, as you call it, is just big traders cashing out their money and invest in a similar business model. That's why I mentioned TKN, not to pump it but given its similarity and offer. Many smart people will follow the trend of selling MCO and buying TKN while cheap until the two will balance at some point. Nevertheless, be smart and make your money now, when you can.
