Sadly 4,000 QRK are virtually worthless nowadays. I guess this can be a good lesson to anyone looking at altcoins. I'll see if I can sell them but for such a small amount I'd guess that the fees will make it not worth it.
Most popular altcoins from just a few years ago are completely forgotten, and I expect the same to happen to the current top 10.
Your 4000 QRK is worth just over $50, traded at Cryptopia. The 0.003
BTC is barely worth the fee to withdraw, but you could exchange it into a more common altcoin again.
At it's peak your 4000 QRK was worth 1
BTC! I've said it before: altcoins are created to get your BTC from you.
