Dutching is usually regarded as a long-term strategy, so it may not be suitable for anyone signing up at Canadian betting sites who is hoping to make a quick profit.
Spotting opportunities for dutching can also take some time, so patience is needed here too. Those who use dutching as a tactic on a regular basis find it can be very profitable, though.
It is worth pointing out that dutching is not a risk-free strategy, though. It is still possible to lose money when dutching, especially if an outsider wins the horse race you have selected.
