BTC vs SPX500

The whole world market is having a hard time right now. The SPX500 index is indicating that because it is in a downtrend. In the coming weeks, there will probably be a big drop in this index, which means that all other markets will be pretty much the same. The SPX500 index is not trading this weekend, so there could be brief flashes of up to 18k on bitcoin.
At 18k it would be nice to short...
