What is the benefit of buying a Bustabit account with the price BTC1 ? Anyone can create an account there for free afaik.

Please don't get me wrong, I'm not a sales trasher. Asking to gain some knowledge about the specialty about the account.

I can only see KLITZ at top of leaderboard except this I can't see anything...
Does Bustabit provide any benefit to top of leaderboard users? I quitted Bustabit more than a year ago.

TIA
