There are few user who are changing swap.hive to LEO and sending LEO to buy LBI. This is mainly for them to check the price.
Even if you are earning LEO and let say you want LBI, If LEO Bid price is 2.42 and LBI ask price is 2.35, what is more beneficial? Sell your LEO for 2.42 and buy LBI at 2.35 instead of doing token transfer to lbi-token.
Only thing is, market keeps changing and so your strategy.
