Few days ago I was day trading [Revain $R](https://coinmarketcap.com/currencies/revain/) on [Kucoin](https://www.kucoin.com) exchange when I saw great opportunity for crypto arbitrage. So I bought some R on Kucoin and wanted to sell it on [Cryptopia](https://www.cryptopia.co.nz). Withdrawal from Kucoin was really fast but deposit on Cryptopia was lagging. It took more than **36 hours**! After I read their support forum I discovered that you should check their Coin info page [https://www.cryptopia.co.nz/CoinInfo](https://www.cryptopia.co.nz/CoinInfo/) where you can see wallet connection and their block height.

Then you should compare it with last block on your block explorer -> in my case - Etherscan.io.

And you see, their wallet is  5095972 - 5093200 = **2772** blocks behind. So it will take more time to process it. 

Happy Trading!
