There are many coins on mainnet so it's not something that will cause a massive spike. However ZEUX news and other partnerships will lift QTUM as we just witnessed recently. We should look forward to more big news, good times are coming
Not every time besides it depends on the popularity of the token or a coin, Main net itself seems to common news nowadays as i observe with those altcoins but not all of them has a good price movement. Moreover surprise announcements that pop ups on the web makes more excitement that leads to a big pump, All i can say Qtum is a solid one and i see a possible more great things and news incoming.
