NuclearVision wroteGuys.. Theoretically, they shouldn't have much LBP since, well you saw the rate. Don't overthink this, there's nothing such as free money, people are not stupid they won't buy Lbp for high and sell it to you for low.
It's not about the people's stupidity, it's just different demand and supply in different markets.
Even in Lebanon you can find two completely separate rates, buying in one whilst selling in the other will make you profit. What you're doing is making profit off the spread and market price difference among exchanges.
Eventually, if everyone does this, the market will regulate by itself.
