RED Coin Shop: Upcoming Tumblr Event

Making the cost of the cubes around 100 coins would hurt the average player more than it would the people who have 30,000+ coins, it wouldn't change anything, except that their thousands and thousands of cubes would be a few thousand less.

Not really. RED coins are the easiest coins to farm in the entire history of the game. The fact that playing zero gives 500 coins alone makes that true, and that's more than enough to max out your cubes/prots for your account/character. Unless you're going to argue that playing zero and getting 500 coins isn't something the average player can do, which straight up isn't true.

And from nexon's perspective and logic, thousands less free cubes is thousands more not free cubes sold.
