Are there any limits to this though?
Imagine you have 0.01 btc, can you play with 100x and thus trade using 1 btc?
Also I don't get exactly the short and long positions.
When you use leverage, are you still using the regular buy or sell BTC? Then later either sell it high or buy it back low?
Thanks a lot.
From what I have observed, you are not yet ready for actual margin trading. This kind of trading needs a lot of time and patience. When you are using a leverage, the higher the leverage, the higher your chance to loss big money or the higher chance to gain big profit. However, if you are a beginner I suggest you use 5x - 10x leverage.
Short position means you are selling your position/bitcion at a higher price than the current market.
Long position means you are buying position at a lower price.
Just always think of this : BUY-LOW, SELL-HIGH.
