So I live in the U.S and I have family in Korea. Obviously there is a great opportunity for arbitrage but was wondering if there were any downsides to it. I would buy bch/btc/eth here then send it to my cousin in Korea and she sells right away for 50-60 percent more. Is there anything wrong with this plan??
Wow that's cool:) actually arbitrage helps in keeping the price of securities across the markets more or less same and therefore it help in better price discovery of an asset and also put an end to price variances in securities across various markets. It helps also in making the financial markets more efficient because imagine if there were no arbitrageurs than stocks would have kept trading at different prices in different markets leading to speculation by few individuals would have damaged the real investors confidence in the stock market.
