which means you'll end up with 36000 gold in 6 hrs at the cost of 20 gems
checking with the wiki, to buy 36000 gold will cost you 54 gems. You'd be saving 34 gems to get the same amount if you were to boost it.
HOWEVER, the only downside is the time factor of 6hrs. so it'll be better to boost to when you're under a shield that's going to last longer than 6hrs.
