Other concerns arose regarding the discovery of the assets. Some were worried about possible conflicts of interest, particularly in relation to Kim's 2021 proposal of a bill that would delay taxation of crypto profits. Others were worried about the source of the funds used by Kim for crypto trading; Kim claims he did not receive money from anyone to use for trading, and obtained the money through the sale of stocks.
On May 10, the Democratic Party recommended Kim sell his crypto holdings, and launched an investigation. Kim said later that day that he would perform the sales, and "transparently disclose data to the investigation team and undergo the inquiry faithfully".
On May 14, Kim resigned from the Democratic Party "for a while", continuing to deny the allegations but expressing wishes to not burden the party and its members over the controversy.
The subsequent day, Korean authorities raided the offices of Korean crypto exchanges Bithumb and Upbit in connection to the scandal, seeking transaction records and other information. Kim was reported to use those services for his crypto wallets.
