WOW, I'm surprised, that's a huge amount,
the hardfork issue keeps the holders of Bitcoin selling their coins,
which causes a lot of unconfirmed transactions and the slowly falling Bitcoin price ...
Hard fork issue? There isn't an issue at all. People bought the market up just for the purpose of having more S2X coins after the chain split, but there is no split at all, so these people are unloading their coins again. It's greed, and that's really it. Unconfirmed transactions right now have to do with a higher overall usage, and a mild spam attack. If miners don't mine empty blocks, which is something that Antpool does on a regular basis, and stop spamming the network in an attempt to make Bitcoin look bad, and of course to boost their fee income, mempools by far wouldn't be as stacked as they are now.
