Clarification
"Conditions are not met to open bookmaking to all sports games, such as the Tour de France for example, since there is no market yet"
There probably *is* a market, given the amount of excitement events like the Tour de France, football matches, Rugby championships and so on produce. It's just that the French government doesn't allow betting on them to any major extent and certainly doesn't go out of its way to advertise what it does allow.
