It may seem very enticing to do arbitrage nowadays because of possible big profit when you buy the coin in low position, then sell it high. However there are risks. For sure the security have been tight at the present given that the exchangers have been informed about the abuse of platform and services. It's also possible that the exchangers have come up with blocking and banning bots or those who don't belong in that specific location where the price of coin is low. Or maybe, even if you bypass, you can't sell it in other place because it is only exclusive (the buy and sell) in that specific place.

Just like certain products that you can buy cheaply in a certain country. Sometimes these products aren't allowed to be distributed and resold outside the country's premises. It's just exclusive and intended to be consumed by the native citizens.

When checking Bitcoin prices, you need to keep in mind that there is no specific global Bitcoin price standard. Bitcoin is not tied to any currency, country or exchange. The question is the same as if you were asking: “Why is bread more expensive in this supermarket, or in this city/country compared to other countries?”. The short but precise answer is “because of supply and demand”. and maybe the transfer fee in South Korea is more expensive than other countries, I haven't tried it but this is my opinion.

Bitcoin now reached $50k value and those who bought at $29k during the dip, already have huge profit. Holding bitcoin for a long period of time is really profitable. Buy low and sell high will give you profit but most others have huge losses due to fear, impatience and lack of knowledge about it . Investing in crypto is risky, so be careful.

Users can search for information about which countries are prohibited from using the trading platform before they create an account in the terms and conditions of the platform. I don't like arbitrage trading although I see an opportunity to make a profit. Confirmation time will be one of the bottlenecks during arbitrage, when the network is busy then I believe you will miss the opportunity to sell it at the best price. I am also not used to doing KYC on many trading platforms because I want to keep my personal data confidential and secure. Some exchange may still be trustworthy because of their reputation, but we still have to weigh the risks.

This ironical and the difference in price usually balance within minutes, and I don't think Binance could stand that low to allow such thing to happen to them when they know that they are the best. Even though it's not on Binance it's happening, please don't waste your time cause this might be a trick especially to those exchanges that has no worth and does not k ow there right from there left. This might be a means to stock investors who are greedy into there shity exchange entrapping funds inside there exchange.

Yes, this is critical info. There's no pointing buying lower on one exchange send it over to the second one and not have it confirm on time or worse be pending forever.

There have been a couple of times where this has happened and when using external exchanges not so familiar, I agree, the risks are higher.

Arbitrage opportunities are not that rare, they are there you just need to look and find them and then plan accordingly - but yeah, it can be a lucrative option for some 

It's true that each exchange usually has a different Bitcoin price, but doing arbitrage trading is not an easy thing to do. We have to take into account
many factors when we are going to do arbitrage, starting from the withdrawal fee and also the estimated time needed. Because usually the price
difference between one exchange and another exchanges moves very quickly, don't let our Bitcoin price drop to no different from the previous exchanges.
Moreover, we move our Bitcoin to exchanges that do not have a good reputation, it will be very risky. I do not recommend making a profit through
arbitrage trading, because the risk that will be faced is too big.

Arbit trade happen in all coin but before doing that you need to checklist

- Legitmate of the Exchange ( its really important because there's bunch scam exchanger)
- Transaction Fee as you know bitcoin fee are higher
- spread of the orderbook
- transcation speed some chain like bitcoin is slow because exchange paid fee at normal rate or below

4K spread is something odd to me you better check first
