Saylor is pushing institutional adoption of Bitcoin at the Goldman Sachs conference, saying it’s a good thing for the market.

Saylor doing the work to drive institutional adoption of $STRC.

A good thing IMO, as the current investor base is mostly retail, and lettuce-handed.

This week at Goldman Sachs’ Digital Assets Conference in London, I discussed Bitcoin, Digital Credit, and the future of capital markets. Extraordinary venue. Exceptional audience. https://t.co/z5Ji66WbYu

Bitwise CIO predicts Bitcoin will hit bottom this autumn and start a new bull market, advising investors to stay focused.

Bitcoin's Next Big Move Could Start This Fall! 🐂

Bitwise CIO Matt Hougan believes the recent volatility surrounding STRC is a typical late-cycle shakeout rather than a reason for panic. According to him, $BTC is approaching its bottom, with market conditions aligning for a potential trend reversal.

His outlook? A new Bitcoin bull market could begin this fall.

Smart money often positions itself when uncertainty is at its highest.

The next major move may reward those who stay focused instead of chasing emotions! 🧠

Open source is something that you should look for when evaluating a project. Open source doesn’t guarantee perfect security, but it gives you the ability to verify it and lacking that, you can lean on people with expertise to audit the code for backdoors, vulnerabilities, or bad practices.

A great example of auditing power is @liz315 CEO
@LeastAuthority.

@TheVladCostea spoke to her in a recent episode of the show.

If social engineering, the origins of famous hacks, Zero-Knowledge Proofs and the growing demand for privacy tech is what you're all about, then you definitely need to Bitcoin Takeover Podcast and chill.

關於 Bitcoin

Bitcoin (BTC) is a digital asset and a payment system invented by Satoshi Nakamoto who published a related paper in 2008 and released it as open-source software in 2009. The system featured as peer-to-peer; users can transact directly without an intermediary. Transactions are verified by network nodes and recorded in a public distributed ledger called the blockchain. The ledger uses bitcoin as its unit of account. The system works without a central repository or single administrator, which has led the U.S. Treasury to categorize bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed. Bitcoin is more correctly described as the first decentralized digital currency. It is the largest of its kind in terms of total market value by now.
