You may already be familiar with Exchange Trading, which is available on most cryptocurrency exchanges - including CoinMetro!
Here are the main differences between Margin and Exchange trading:
Do wallet balances update immediately after an order is filled?
No - instead an open position is created which has a floating profit or loss (P/L) that automatically updates as market prices change
Can leverage be used?
Yes - leverage can be used (up to 5:1 at CoinMetro) to amplify potential gains and losses
Can the trade value exceed available funds?
Can you sell (short) an asset that you don't own?
What is the maximum trade size?
The available balance of the asset being sold
Free margin x leverage equivalent value
When do wallet balances update?
Once the order has been filled
Once the position is closed
For which assets do the wallet balance(s) update?
The assets being exchanged
The settlement currency. At CoinMetro, this will be your primary collateral currency
Can I withdraw my bought assets to an external wallet?
Settled profits can be released from collateral and withdrawn; however, other assets in open positions cannot
In summary, Margin Trading provides the most flexibility if your main goal is to generate profits with added leverage.
If you instead want to purchase cryptocurrencies for long term holding and/or for trading without greater risk, then Exchange Trading would be more suitable for you.
