I'm new to cryptocurrency and still learning what is this. I was thinking that why there is a price difference between exchanges for a same coin. Rates on cex.io is too high while coinbase has a very low. I noticed that the difference is around $1000-2000 for bitcoins. This is a huge difference.
Depends on the trading volume of the said trading platform. Thank for example, Zimbabwe exchanges, the price of a bitcoin is at a premium, because most of them are putting a lot of their money into the market because its their mode of storing their wealth. And then we have the South Korean market which dominates the trading volume per 24 hours. They too have bitcoin price well above their Western counterpart because the trading volume is huge on that side of the planet.
So its not surprise that we will find different bitcoin price on every exchange. That's why we also have what we call "Arbitrage", wherein you will buy bitcoin on a trading platform where the price is lower and then sell them at a higher rate on another platform. Instant profit on your end.
