Spot Exchange vs CFD, and Volatility-Scaled Stops
On a spot exchange you buy the coin outright, so your position size in coins is your dollar risk divided by your stop distance, with no leverage math needed. Through a CFD broker the same size applies, but leverage sets the margin the broker holds. Either way, size from risk first and think about margin second.
Because crypto is volatile, scale your stop to the instrument rather than copying a forex distance. A stop that is tight on EURUSD can be far too tight on ETHUSD. Set the stop where the idea is wrong, accept that it will be wider in dollars, and let the calculator shrink the position so the risk stays constant.
