I will add onto Jcbrefs response by also pointing out that the Facebook page and discord server will also occasionally have such events giving out Miracle coins every so often. 

Max guild member amount reaches the cap at level 10 so level 11 and 12 are just for guild skills which are very powerful for a reason   Making guild leveling cheaper would devalue globe and guardian by making them more accessible   And in competitive events of warspear having globe available for 220k gold would be gamebreaking
