Thanks for the reply but you didn't answer my question at all, you simply described what leverage trading is. I know what leverage trading is. I'm asking about a specific scenario or form of arbitrage, where by one would earn a return while only subject to counter party risk of default.

Another method would be buying spot, and selling a future contract for a future date listed at a higher price. I asked about my example though because I believe the returns via funding would exceed the spot-future contract difference.

Thoughts?

Let's say I buy 1 BTC at 60k. Then I short 60k perpetual futures contracts on an exchange (and collect funding assuming positive funding longs pay shorts). Is this a good relatively risk free way to make a decent return, or am I missing something? Thanks.

I'm selling BTC in Toronto at Bitstamp price +1%.
