Aside from the reputation and security of betting companies, which we consider imperative, there are more aspects to consider.
Among them are for example what betting features they offer.
It is very rare to find an online betting site that does not offer live betting these days. The option to bet on football during matches is too popular to not have as a feature. However, some betting companies do this better than others.
Usually the bigger betting sites offer much more options for live betting, both in terms of available leagues and matches, but also in terms of markets (next goal, next goalscorer, next yellow card etc).
Among the best betting sites for live betting are Betway and Intertops.
The cash out feature means that you can cash out your bet early. For example if your team is in the lead, and you want to secure some money, you can cash out part of your winnings and not risk the opponents catching up.
This feature is prominent at Betway, where you can both cash the entire bet out, or just part of it, called a partial cash out.
