if there is a bull run when Ethereum, Bitcoin, EOS, Stellar and all other coins are greatly increased, will some of my coins be worth again?
Will a bull run affect the price of my token?
It depends in the coins that you're holding.
If your coins are dead/shitcoins and has no demand for investors to buy even the bull run occur then the value will remain as is.
But usually if the price of well-established coins increased majority of other altoins follow, thus there's still possibility.
