History of Bithumb

The founding company behind Bithumb is called BTC Co. Ltd. There is little information available from Bithumb or BTC Korea regarding their executives or employees, though. On their website, Kim Jae-Wook is listed as the current CEO of Bithumb, but there are no other members listed publicly.

Bithumb was the victim of a hacking attack on June 29, 2017 when a Bithumb employee’s home PC was compromised. The hacker was able to access the personal data of roughly 3% (31,800) of Bithumb users. Only some of those 31,800 users had funds stolen from their account. After the hack, Bithumb provided compensation in the amount of at least 100,000 KRW (~US$86.50) to each affected account. The amount of funds lost from each victimized account varied, but one user reported a loss of 10,000,000 KRW (~US$8700).

It is worthwhile to note that the Bithumb network itself was not compromised; had it not been for this employee’s computer, the hack would not have occurred. Though the hack was unfortunate and affected thousands of people, it can be said that the Bithumb network itself is relatively safe, especially for being one of the largest cryptocurrency exchanges in the world.

Registering on Bithumb

Bithumb supports both individual and corporate accounts. To register as a basic user on Bithumb, you must first start by providing your name and nationality. After that, users have to verify their cell phone and email address. The amount of trading that you will be allowed to do depend on the level of verification that you provide. There are four different trading account levels:

Level 1

Level 1 requires only email and SMS verification. With a level 1 account, you can deposit an unlimited amount of virtual currency into your account, but no KRW. You can not buy or sell any currency as a level 1 user.

Level 2

Level 2 requires further identification confirmation which includes everything from level 1, in addition to a cell phone, submission of the user’s passport, and I-PIN ID confirmation.

Level 3

Level three requires all of the above in addition to a personal or corporate written pledge.

Level 4

Level 4 requires all of the level 1-3 documents as well as proof of residence.

Bithumb and Arbitrage

Savvy Bitcoin traders have kept their eyes on the Bithumb exchange as a possible opportunity to make money off of Bitcoin arbitrage. Arbitrage is the practice of buying something at a lower price in one market and then selling it at a higher price in another. Bitcoin is usually marginally more expensive on Bithumb than it is on other exchanges.

For example, at the time of writing, 1 Bitcoin on Bittrex was priced at US$3854; 1 Bitcoin on Bithumb was valued at US$3862. US$8 is not a large amount of money, but a high volume of Bitcoins or even just a high number of trades could potentially bring in some serious profits.

However, doing this successfully may require a user to either have residency in South Korea or to have a partner with South Korean residency that they can trust with thousands of dollars of cryptocurrency.

Bithumb: Worth Your Time?

While Bithumb is still geared mostly toward its base of South Korean users, it is relatively easy to understand and operate for English-speaking users. With excellent user support and a reputable record of solving problems and providing compensation for exchange hacks or errors, Bithumb seems to be a worthwhile exchange. Bithumb is quite a large exchange, and its trading volume will undoubtedly continue to grow as more currencies are added to its platform.
