Mt. Gox vs. Bithumb: That Was Then, This Is Now

Bithumb now shares something in common with the Tokyo-based shuttered bitcoin exchange Mt. Gox — both suffered a hack on about the same date, June 19. It’s a club that no exchange wants to belong to and that Bithumb happened on the seven-year anniversary of Mt. Gox’s maiden attack has to be more than an eerie coincidence.

It’s a stark reminder of the risks involved with keeping funds on an unregulated exchange, vulnerabilities that cost South Korea’s Bithumb some $36.6 million in digital cash and Mt. Gox $450 million in hacked bitcoin and its future. The Mt. Gox theft unfolded over a series of hacks that culminated in 2014. Though it’s still early on in the Bithumb hack, it appears the South Korean exchange will recover from the security breach. So what do we know now that we didn’t on June 19, 2011?

Then vs. Now

Former Coinbase official Nick Tomaino, who is also the founder of crypto fund 1 confirmation, reflected on the Mt. Gox hack in what proved to be a prescient tweet given the Bithumb attack that was about to surface.

The thing to note about Mt. Gox is that the Japan-based exchange in 2011 controlled most of the BTC trading volume, approximately three-quarters of it by average estimates — more if you ask Tomaino. Since bitcoin fever caught on in 2017, there are more than 500 cryptocurrency exchanges on which trading volume is shared. Binance boasts the highest trading volume and captures nearly 15% of bitcoin trading. It’s much less than Mt. Gox days but still a little high.

The other thing to note is that the Mt. Gox hack or actually hacks, as there were multiple attacks on the exchange over several years, was a mysterious event that was shrouded in controversy and mistrust of a key executive. Bithumb, on the other hand, confronted the hack seemingly right away on Twitter and has not let any grass grow under its feet in the interim, which is a key difference in the way Mt. Gox was handled.

Also, the bitcoin price didn’t tank in response to the Bithumb hack. It traded lower for a while, but less than 24 hours it was back in the green, which is a reflection of the fact that bitcoin trading is no longer dependent on a single exchange.

Charlie Lee, creator of Litecoin (LTC), the No. 6 cryptocurrency by market cap, was among the first to respond to the Bithumb hack. He tweeted:

Indeed, Bithumb does expect to be able to cover the losses via their reserves.

Crypto Security

It’s still early on in Bithumb’s security breach, and more details are sure to emerge in time. In the meantime, it’s a good idea to use the hack as an opportunity to examine the security of your cryptocurrency investment portfolio. There are several hardware wallet options out there for you to choose from — whether it’s Trezor or Ledger Nano S, to name a couple — and as Charlie Lee advised, “only keep on exchange coins that you are actively trading.”
