Drop them. Yes people say that you lose too much but seriously. Drop 'em. It's only 40% which yes if (1b -> 600m) but (1m->600k) really isn't that much. Stop spamming "Hire my tutor they are [insert bull**** here]" DROP EM
Some people swear against dropping. Think of it as gaining 60% not losing 40% if they aren't getting hired
Dropping us a waste of hard earned cash.just keep for stats and move on.if in future they upgrade you get cash back.if it's a 50-100-or 200b tut you would be an idiot to just drop.patience is a virtue pimd
