Facebook finally adding the bulk-delete feature to remove your embarrassing old posts
Facebook is finally adding a new feature called Manage Activity that lets users delete their old posts. It can be used to remove individual posts or in bulk, and Facebook announces it will offer filtering choices to help find posts with specific people in them or within a particular time range. The feature will be available on Facebook’s mobile apps first.
According to Facebook, the feature is intended “to make it easy for you to curate your appearance on Facebook to reflect who you are today more accurately.” As an example, it suggests that someone might want to delete old posts when they’re about to start working full time after college or delete posts that remind them of a past relationship.
There are a couple of different options to remove a post from the timeline. It can be sent to the trash, where it will be removed from public viewing immediately but only permanently deleted 30 days later. (Posts can be manually deleted sooner.) Alternatively, a post can be archived, which means it’s no longer public but can still be viewed privately.
Twitter is another public platform where you might want to delete your old posts. However, the company has yet to provide an official bulk-delete tool, which has proven to be a problem when old tweets have been dug up in an attempt to discredit or otherwise cause trouble for people. In the absence of an official tool on Twitter, various third-party tweet deletion services have sprung up.
Manage Activity is Facebook’s latest attempt to give users more control over their data. Last year, it finally launched its Clear History tool, which lets users disconnect their web browsing data from their Facebook account. However, despite its name, Clear History doesn’t delete this data; it just removes the link between it and your Facebook account.

Hashdex Unveils Innovative Dual Crypto ETF Targeting Bitcoin and Ethereum
In a strategic move to capitalize on the growing interest in cryptocurrency investments, Hashdex has announced its plan to launch a new Hashdex Nasdaq Crypto Index US ETF, which will track both Bitcoin (BTC) and Ethereum (ETH).
On Tuesday, Nasdaq published the 19b-4 application for this groundbreaking ETF, marking a significant development in the crypto investment landscape. Unlike traditional ETFs that focus on a single cryptocurrency, Hashdex’s new offering aims to provide exposure to the two largest digital assets by market capitalization simultaneously.
The decision comes shortly after the SEC’s approval of Bitcoin Spot ETFs earlier this year and amidst ongoing evaluations of various 19b-4 applications for Ethereum Spot ETFs in May. This move positions Hashdex uniquely in the market, allowing investors to benefit from the potential of both BTC and ETH in a single investment vehicle.
Bloomberg expert Seyffart weighed in on the announcement, noting that a dual BTC and ETH ETF from Hashdex, weighted by market capitalization, is a logical progression in the evolving ETF landscape. While Hashdex opted not to pursue an Ethereum Spot ETF application alongside other major issuers, their focus on a hybrid ETF underscores their commitment to innovation and strategic diversification.
According to the application, the Hashdex Nasdaq Crypto Index US ETF will include cash holdings but refrain from incorporating additional cryptocurrencies. If approved, custodianship will be entrusted to industry leaders Coinbase and BitGo, with the SEC’s final decision expected by March 2025.
This initiative marks a significant milestone as the first US spot ETF application encompassing more than one cryptocurrency. Current plans allocate approximately 74% of the ETF’s portfolio to Bitcoin and 26% to Ethereum, reflecting the respective market capitalizations of these digital assets.
While similar investment products are already available in Europe, such as Bitpanda’s Bitpanda Crypto Index 5/10/25, which tracks the largest cryptocurrencies by market cap, Hashdex’s dual crypto ETF aims to provide US investors with a novel opportunity to diversify their crypto holdings within a regulated framework.
In summary, Hashdex’s innovative approach to launching a dual BTC and ETH ETF underscores the increasing integration of cryptocurrencies into traditional financial markets. As regulatory approvals progress, this ETF could pave the way for broader acceptance and adoption of digital assets among institutional and retail investors alike.

Trader burns $340,000 in one minute with TrumpCoin
A Memecoin investor had to pay a heavy price for his mistakes. The trader lost over 340,000 US dollars in one minute. How the faux pas could have happened.
Memecoin Trader Loses Over $340,000 in a Minute Due to Fraudulent Transaction
A memecoin trader has reportedly lost more than $340,000 in less than a minute, according to the on-chain analysis service Lookonchain on X (formerly Twitter). The incident involved two transactions on Solscan, revealing a significant financial mishap.
On June 18, the trader attempted to exchange 2,500 SOL (approximately $342,000) for the newly launched TrumpCoin (DJT) using a trading bot. However, instead of receiving the legitimate DJT tokens, the trader was duped into obtaining 92,000 fake DJT tokens created by fraudsters. These fraudulent tokens were worth significantly less than the genuine ones.
The transaction took place through a “fake” liquidity pool on Raydium. This pool was not sufficiently funded and was filled with DJT tokens created by scammers. When the trader attempted to convert the DJT tokens back to Solana, the scam became evident. Unfortunately, by this point, it was too late, and the trader’s initial 2,500 SOL had dwindled to just under 5 SOL—a loss of over $340,000. For the fake DJT tokens, the trader received only $673.
The DeFi (decentralized finance) space is rife with such scams, where fraudsters set up fake liquidity pools to exploit traders’ mistakes. Some decentralized exchanges (DEXes) issue warnings to users about these scams, but trading bots typically do not provide such alerts. This lack of warnings is especially problematic with newly launched coins, where traders can easily fall into the trap of exchanging for the wrong tokens.
This incident highlights the perils faced by crypto investors beyond the usual price volatility. The affected trader remarked on X, “Life goes on,” reflecting a resigned acceptance of the loss.
Despite this unfortunate event, the world of memecoin trading has its success stories. Some traders have achieved remarkable profits in short periods. For instance, one trader became a millionaire in just five hours, while another made a profit of $9.5 million in ten days by trading the celebrity token MOTHER, associated with US rapper Iggy Azalea.
This stark contrast between potential gains and significant losses underscores the high-risk nature of the cryptocurrency market, particularly in the memecoin sector. Investors are reminded to exercise extreme caution and conduct thorough research before engaging in such trades.
