Here’s what happened in crypto today

Today in crypto, the post-US election honeymoon looks to be over as cryptocurrency exchange-traded products (ETPs) recorded a relatively minor $47 million of inflows last week after a significant sell-off in Bitcoin investment products, SlowMist’s chief information security officer said a list of seven million OpenSea user emails leaked in 2022 has now become public and available for scammers, and Michael Saylor teased another Bitcoin purchase by MicroStrategy for the tenth consecutive week.Crypto ETPs record $47 million inflows last week amid Bitcoin sell-offInvestors poured about $1 billion into crypto ETPs in the second trading week of 2025, which was largely offset by $940 million in outflows, crypto investment firm CoinShares reported on Jan. 13.The massive outflows were triggered by the release of new macroeconomic data and minutes from the US Federal Reserve, which pointed to a stronger US economy and a more hawkish Fed, CoinShares research lead James Butterfill said.“This suggests that the post-US election honeymoon is over, and macroeconomic data is once again a key driver of asset prices,” he stated.Bitcoin (BTC) investment products saw inflows totaling $213 million for the week of Jan. 6-10, despite having the biggest outflows relative to other digital assets later in the week.So far in 2025, Bitcoin remains the best-performing asset with year-to-date inflows of $799 million, the report noted.Following the sell-off, the total assets under management (AUM) in Bitcoin ETPs dropped 3.5%, from $130 billion the previous week to $125.4 billion.Millions of leaked OpenSea user emails now public: SlowMistOver seven million email addresses compromised in an OpenSea email vendor leak in 2022 have recently been “fully publicized” online — giving scammers a new treasure trove of information to work with, warns a SlowMist executive. “Remember the attack on the OpenSea mail service provider in [2022] that led to the leakage of emails? The leaked email addresses have now been fully publicized after multiple disseminations,” SlowMist’s chief information security officer, “23pds,” wrote in a Jan. 13 post on X. Speaking to Cointelegraph, 23pds explained that while the attack occurred in June 2022, the data had not been made public until recently, meaning “all groups of attackers can use this information to go phishing and scamming.”“Previously, it was not made public. Now all the leaked data has been made public in its entirety and is available to anyone who wants it.”OpenSea, one of the world’s largest non-fungible token (NFT) marketplaces, first warned customers of a data leak on June 29, 2022, after discovering that an employee of Customer.io — its email automation platform — leaked the list of OpenSea customer emails to an outside party. Saylor hints at impending Bitcoin acquisitionMicroStrategy (MSTR) co-founder and Bitcoin advocate Michael Saylor has posted the MicroStrategy Bitcoin chart — signaling an impending Bitcoin purchase by the company on Jan. 13.“Thinking about the next green dot on SaylorTracker,” the executive wrote to his 3.9 million followers on the X social media platform.According to the SaylorTracker website, MicroStrategy currently holds 447,470 BTC, valued at approximately $42 billion, and is up 51% on its BTC holdings — representing an unrealized gain of roughly $14 billion.The company’s Bitcoin treasury strategy has drawn mixed reactions from the investment community, with some praising Saylor’s approach of financing Bitcoin through debt, and others warning that sudden swings in Bitcoin’s price could send MSTR shares crashing.
