TRADING BOTS
Too many trading bots in play have made it quite hard to catch those coin price gaps between different exchanges. The coin price gap will be long gone even before the transaction is confirmed
VOLATILE COIN PRICE
Successful crypto arbitrage requires when the price of a coin is not so volatile but in the case of coins like Bitcoin, the price can change by $50 in matter of minutes. You may end up buying it thinking you have bought low, you try to transfer it to another exchange only for the price to drop there too within minutes before even the transaction is confirmed.
SLOW TRANSACTION CONFIRMATION
This is the case especially for Bitcoin, You have to wait for more than about 20 to 30 minutes of which the price or coin market gap will have be long filled up.
WALLET MAINTENANCE
Some coin market price gaps are just due to the different wallet maintenance schedules in different exchanges. You buy a coin and try to transfer it to another exchange so as to sell high only to realize that the other exchange's wallet is under maintenance and they do not accept a deposit of that coin
DECEPTIVE MARKET PRICE ON DIFFERENT EXCHANGES
This is common with altcoins since some have low trade volumes, for example the sell price you may see in the exchange you want to transfer your coins to and sell may not be reflected well in the order-book. It could just be a small sale volume which was made at a very high price yet in the order-book the next bid order is either at the same price range as the price with which you bought the coin or even slightly lower implying will just make a loss if you dare to transfer the coins and sell them.

Those are the few shortcomings that i experienced and i thought i could share with you.[/list]

I agree with this. It is nearly impossible to do arbitraging due the reasons mentioned above. I would like add another reason. Different trading fees and different deposit/withdrawal fees also make it difficult to do arbitraging.
There could be rare opportunities if you choose a centralized exchange and a DEX as there is less room for bots to identify arbitrage opportunities in DEXs.

Sometimes it is worth to do if we have better capital,the profits can't be made if we arbitrage with few thousands of USD maybe it will be profitable if we trade few bitcoins but not always.For example coinbase is one of the place we can buy bitcoins at good price and go to some exchange with much lesser transaction speed and fast withdrawal approvals.
