Second Bitcoin-Linked ETF In The US To Begin Trading On Friday

The fund, which tried listing as BTFD, has backtracked and will list under the ticker symbol BTF.

  • The second bitcoin-linked ETF in the U.S., the Valkyrie Bitcoin Strategy ETF, is set to begin trading on Friday.
  • The fund, which tried listing as BTFD, has backtracked and will list under the ticker symbol BTF.
  • The third bitcoin futures ETF is set to launch on Monday.

Valkyrie’s bitcoin-linked exchange-traded fund (ETF) has beaten VanEck in the race and will list the second bitcoin futures ETF in the U.S. on Friday, October 22. VanEck is set to launch its own offering on Monday, October 25, the third of its kind in the country.

The Valkyrie Bitcoin Strategy ETF ($BTF) will start trading on Friday, according to senior ETF analyst at Bloomberg Eric Balchunas. The asset manager likely exploited “its status as a first time issuer [to] skip the queue by requesting to become effective,” Balchunas previously said, leading Valkyrie up the line and ahead of VanEck.

The bitcoin ETF race in the U.S. has been fierce over the past year. After several delayed applications, the Securities and Exchange Commission finally allowed an ETF linked to bitcoin to start trading on October 19, the ProShares Bitcoin Strategy ETF (BITO). But with one caveat  none of the three offerings yet approved will buy or hold BTC directly.

Instead, the set of ETFs being listed in the U.S. have all been bitcoin futures ETFs, meaning they seek bitcoin exposure through futures contracts of BTC traded on the Chicago Mercantile Exchange.

In September, SEC chairman Gary Gensler commented that derivatives-based BTC ETFs would be more likely to be approved by the regulating commission. Fast-forward one month and a handful of bitcoin futures ETFs are successfully lined up for listing in the country.

Today, the first bitcoin-linked ETF to list in the U.S. became the first ETF ever to reach $1 billion in assets under management (AUM). The gold ETF GLD held the previous record as the quickest exchange-traded fund to hit $1 billion in AUM  three days.

I think of a situation that attacker can steal data from AES encrypted table without knowing the key.

Assuming that the table is encrypted with same key but different IV:

  1. Attacker signs up for a new account in an application normally.
  2. Application creates the account and inserts a new row (2nd row in table below)
  3. Somehow attacker found a vulnerability in application to run SQL injection
  4. By SQL injection, attacker replaces cipher of his row with Victim’s value
    e.g. aes_cipher_2 -> aes_cipher_1 and iv_2 -> iv_1
  5. Attacker signs in his own account
  6. Attacker goes to the profile page, then application decrypts Victim’s data (aes_cipher_1) and shows the plaintext to him.
