Thanks for sharing and margin trading can be a great way to grow the account if done right.
Just wanted to share that for anyone wanting to try this, don't deposit your SBD into polo just yet. They're still having issues with their wallet. My deposit from earlier today is still missing.
Exactly. You can just buy Ethereum if you think that it is going to go up. And use it as a collateral to sell Ripple (short position in margin trading). If your both predictions are right, you will make more profit than just making single Ethereum trade. More tools, more profit!
