I haven't heard about Altar coins, was that a new altcoin? Or are you pertaining to alternative coins? but based from your topic, the reason I can see for altcoins market value to spike is the hashrates, miners around the world will compute transactions even faster, in that regards, it will be convenient for people to create transactions personally since it is fast, reliable and secured. More and more people will accumulate volumes of altcoins so its market value might increase as well based on the demands of people.
