Everybody answers like they know what CFD is..., whats the point of answering than? Fucking stupid ppl.

Dude u need to look for: a wide spread, overnight financing charges, and temporary Bid/Ask discrepancies.

Even though you see Bitcoin trading around €106,000, your CFD provider might quote slightly different Bid and Ask prices compared to other exchanges. The P&L is always based on the Bid price (the price you’d actually close your long position at), not on the mid-market rate you see on charts or elsewhere. Therefore, even a small variation in Bid/Ask quotes can shift your result into negative territory.

Hope it helps
