It costs 200 bee to get premium.
It takes 1000 bee staked to keep the bot on.
Each token you want to trade takes 200bee staked.
I'm very happy with the bot.
Watch for falling markets and manipulators, though, it's easy to get caught on the wrong side of a falling market.
I mitigated this by only trading coins I would hold anyway.
