In my heart there are a few questions that until now have not been solved or maybe from other members there are also like me. my question is why the price of some crypto from one exchanger to another is different, for example coin A in binance 2$ and in one of the other exchange coin A is 2.1$, it's a little bit difference, whereas coin is same, it should be coin same price must be the same.
what's your opinion all about sir?
You should look at the trading volume of the exchange. If the exchange with large trading volumes at the same altcoins is usually not significantly different, the liquidity is very good and it represents the price of the altcoin in the market. Some small trading floors may have higher value but the liquidity is very low. This difference comes mainly from the trader each exchange.
