I disagree with all totality,gambling is made for mature minds who is able to take responsibility for his or her actions whether winning or losing and not one ready to blame or shift responsibility why he wins or lose. Kids Dont own responsibility so they should outrightly be disallowed and these are the arguments against Bitcoin in some quarters. Either way there are some sites that disallow below 18 to gamble. If any kid wants to make money should try PTC but not gambling... My 2 cents...
