let me understand better, if you already have your position in USD, what is the difference with shortselling btc ?
if you hold that position, it's the same as shortselling, or not ?
I don't have any position in bitcoins. I have USD that equals 3000 bitcoins or more at 10 dollar/bitcoin.
understood that, so what's the need to shortsell, if your position already in USD ?
if you are betting on a lower future rate, you can keep the dollars and buy btc later.
