On March 7 a report addressed to the Tokyo District Court revealed that a Mt. Gox bankruptcy trustee – Nobuaki Kobayashi – may have contributed to the three month downtrend in the cryptocurrency market.

Over the past three months, Nobuaki Kobayashi has sold over $300 mln in Bitcoin on two public exchanges. Some critics believe Kobayashi's sales put so many Bitcoin back into circulation, that the sales contributed to severe drops in the price of Bitcoin. Bitcoin has declined 51.6 percent since its Dec. 17 peak of almost $20,000, and it is suspected that Kobayashi was a significant factor in the decline.

Who is Nobuaki Kobayashi?

Nobuaki Kobayashi is a lawyer at the Nagashima Ohno & Tsunematsu law firm headquartered in Tokyo. The District Court of Tokyo assigned Kobayashi to be the Mt. Gox Bankruptcy trustee in a document released on April 24, 2014.

Report details

According to the Tokyo District Court report Kobayashi is planning to consult with the court on how the sale of the remaining 166,344 Bitcoin (BTC) and 168,177 Bitcoin Cash (BCH) under his management should be conducted.

“I plan to consult with the court and determine further sale of BTC and BCC [Bitcoin Cash is called BCC in the report - Cointelegraph].” (Mt. Gox report, p. 12)

Nevertheless Kobayashi has already sold 35,841 BTC and 34,008 BCH without consulting the court. "Between the 9th creditors’ meeting [Sep. 27, 2017 - Cointelegraph] and this creditors’ meeting [March 7, 2018 – Cointelegraph], with the permission of the court I sold a certain amount of BTC and Bitcoin Cash (“BCC”) that belonged to the bankruptcy estate," the report cites Kobayashi.

Kobayashi did this to begin paying down the current JPY 45.6 bln ($430 mln) claim that creditors have on the defunct Mt. Gox. Originally, 24,750 claims that totaled JPY 263.5 trln ($2.4 trln) were filed against Mt. Gox. On May 25, 2016, Kobayashi stopped accepting claims on lost funds, rejecting JPY 263.4 trln ($2.4 trln) worth of claims, leaving Mt. Gox with JPY 45.6 bln ($430 mln) of liabilities to creditors.

Although Kobayashi received permission from the Tokyo District Court to sell a certain amount of BTC and BCH, he is being criticized for selling the funds on online exchanges, as this decision has allegedly been the cause of several market disturbances contributing to the downtrend.

Five sales

On February 7, 2018 it was discovered that seven of the Mt. Gox Bankruptcy trustee’s cold storage wallets were involved in transactions to two different hot wallets – wallets hosted on online exchanges - between December 18, 2017 and February 5, 2018.

It could be suspected that since Kobayashi was dealing with relatively large amounts of Bitcoin, some of the $30 mln + transactions made by Kobayashi from the Mt.Gox cold storage wallets are correlated with significant declines in the price of Bitcoin.

At 10:34 a.m. the price of Bitcoin dropped to $12,350.10, a 8.4 percent decrease in the price of Bitcoin from the time of the $80 mln sale. However, Bitcoin finished the day in the green at $14,320.90 – a 6.2 percent increase in value from the estimated sale price.

Analysis

Kobayashi is being criticized for selling large quantities of Bitcoin on two public exchanges. Allegedly, Kobayashi’s sales contributed to the three month downtrend in the price of Bitcoin. But if we look at these seven transactions and five sales by the Mt. Gox trustee, how much of an impact did Kobayashi really have on the cryptocurrency market?

Only two of Kobayashi’s trades had an impact that moved the market more than 5 percent in less than 12 hours. The decline in the price of Bitcoin and the sales on the exchanges occurred around the same time in each instance –10:30 a.m. and 3:30 a.m. respectively. But the market finished 6.2 percent and 7.7 percent above its morning price respectively each day the market dropped more than 5 percent.

Out of the five sales on the exchanges, the price of Bitcoin only finished in the red on Feb. 8. But despite Kobayashi selling $32.9 mln of Bitcoin on the exchange on Feb. 8, the price of Bitcoin only declined 2.3 percent for that day.

On four occasions the price of Bitcoin dropped subsequent to Kobayashi’s sales: Dec. 22, Jan. 17, Feb. 7, and Feb. 8, by 8.4 percent, 10.8 percent, 1.2 percent, and 2.2 percent respectively. Nevetherless the price of Bitcoin rebounded in each instance except for the day of Feb. 8.

Even though Kobayashi five sales represent over $300 mln in Bitcoin being sold over public exchanges, Kobayashi’s largest sale of 10,000 BTC that netted him around $86.6 mln only represents about .55 percent of the entire Bitcoin market cap, nothing to bat an eye at.

Conclusion: Kobayashi’s actions not so significant

The rebound in the price of Bitcoin from the alleged declines caused by Kobayashi may have also been induced by Kobayashi.

It’s possible that investors bought more Bitcoin after Kobayashi drove the price down, which moved the price of Bitcoin back up and caused the cryptocurrency to finish in the green four out of the five sale days.

The correlation between Kobayashi selling Bitcoin and the return on Bitcoin for the day is negatively correlated at -.655240891. This means that the movements in the price of Bitcoin and the amount of coins that Kobayashi unloads on the market move independently of each other.

The data shows us that Kobayashi’s actions were not as significant to the price of Bitcoin in the short run as some individuals believed they were. That being said, the amount of cryptocurrency under Kobayashi’s management could have the ability to create a panic that causes investors to sell off their cryptocurrency – especially if they get a glimpse at a sell wall created by Kobayashi.

When asked by Cointelegraph how the remaining 66,344 BTC and 168,177 BCH under Kobayashi’s management should be sold off, day trader and entrepreneur Tim Rainer said he would prefer to see the rest of the coins under Kobayashi’s management sold off in a drip fed style if they really need to be sold off at all:

“In my opinion they shouldn't be allowed to sell any, but if they did then it should be a drip fed amount. Too many [coins] put back into circulation will cause a price drop and that will cause the traders to get scared and sell. A majority [of investors] jumped onto Bitcoin too late, therefore their profits are small. No panic selling. This happened in January and I lost $30,000.”

Although the daily return and price data show that there is a negative correlation between Kobayashi’s actions and the Bitcoin prices in the short run (daily), it would be best if Kobayashi took a less transparent approach to selling the quantity of coins under his management to avoid frightening investors into another mob-mentality sell-off.
