Recently I saw a post about the Nigerian exchanges and i realized that the buying rate is 20-30{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} higher.

That means that the people in Nigeria buy at +30{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8}, BUT that also means that the Nigerian exchanges buy at +25{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8}.

Simple math:

Buy rate at Coinbase at 11:00 = $926

Sell rate at Nalra at 11:00 = $1148
