sometimes . it depends on the coin . there are also a factor on the price of bitcoin if the bitcoin price is rising the altcoin value increases in my own opinion. Make sure when you are buying a token you better check the website and update of specific coin
You must've heard about my activity tokens, would you like to know what was needed for me to actually succeed? no support of the community, any exchanging service given enough incentive would've listed them and people would've traded them even after seeing theymos implementing merits and no such a thing as activity tokens. current situation with every coin, they have no system in place to use them, people are trading them knowing that there is nothing to use the coins on.
There was a failed ICO recently, the *devs were trying to refund investors, some idiots were buying the useless tokens, knowing the ICO had failed.
