I don't understand the logic of many people shorting $VOXEL ...

How many times have I said it, don't think that just because a coin has a large increase, you should habitually short it with linear thinking. If you just take a look at its market value, you'll realize what kind of foolish thing you're doing. Then, look at the contract open interest, how much is the market value? How much is the contract open interest?

After reading this, give yourself a slap.
