<h2 id="three-things-to-know">Three Things to Know</h2>
<ul>
 <li>Bitcoin Core disclosed three patched flaws, including one that let thousands of Tor-linked nodes trust any stranger.</li>
 <li>Bitcoin trades below both of its key moving averages, and momentum still favors sellers.</li>
 <li>The nearest floor sits far below current prices, leaving little on the chart to cushion a drop.</li>
</ul>
<p>Bitcoin Core developers revealed on Tuesday that a setup flaw let thousands of nodes treat anonymous Tor connections as trusted peers. The bug was fixed more than a year ago, and the advisory reports no attacks.</p>
<p>The disclosure arrives as bitcoin extends a monthly slide and sellers control the chart. Old, patched bugs rarely move prices on their own. The real question for traders is whether buyers can defend the next floor before the decline speeds up.</p>
<h2 id="thousands-of-tor-nodes-trusted-strangers-before-a-quiet-fix">Thousands of Tor Nodes Trusted Strangers Before a Quiet Fix</h2>
<p>Bitcoin Core published a formal security advisory on Tuesday covering three flaws in the node software. Developers patched all three in releases issued in October 2025, so the disclosure arrived about 13 months after the fixes. The advisory reports no attacks.</p>
<p>The Tor issue drew the most attention. Some providers bundled Bitcoin Core with Tor, and in those setups incoming Tor connections inherited whitelist permissions. Strangers could then skip spam and privacy protections. The advisory cites "thousands of reachable mainnet nodes whitelisting all incoming Tor connections." Martin Zumsande and Antoine Poinsot reported the bug. Poinsot privately warned the unnamed providers on Sept. 19, 2025. Nodes that never enabled the whitelist were safe.</p>
<p>A high-severity flaw tied to a rule in Core 28.0 could leave mining nodes unable to build valid block templates until a restart. Niklas Goegge reported it on Sept. 26, 2025. A third bug let one connection stall block processing for 10 minutes.</p>
<p>The timing followed policy. Core discloses two weeks after the last affected release loses support, and the 29.x series hit that point on Oct. 27. Since October, bugs that are easy to rediscover, including AI-findable ones, get immediate advisories.</p>
<p>Markets were already weak. Bitcoin fell 4.7% in the week to Nov 10 and sits about 16% lower year-to-date. It also trades about 41% below its October 2025 record.</p>

<p>Bitcoin traded near $73,000 on Thursday, little changed over 24 hours. The calm hides a rough stretch. The coin is down about 9% over the past seven days.</p>
<p>Price now sits under both of the moving averages traders watch most. A moving average tracks the mean closing price over a set number of days and smooths out daily noise. The 50-day average stands near $79,000. The 200-day average sits lower, near $76,000.</p>
<p>When price falls below these lines, they tend to act as ceilings. Buyers who entered near those levels often sell into any rebound to get out even. That gives bitcoin two layers of overhead before the trend can turn. The closer barrier is the 200-day line, which also marks the longer-term trend.</p>
<p>The slide started well before Tuesday's advisory. Bitcoin has lost about 10% over the past 30 days, so sellers were already in charge when the Tor details came out.</p>
<p>Because the flaws were fixed long ago and never exploited, the advisory should trigger little new selling.</p>
<p>Thursday's flat session looks like a pause after a heavy week, and one quiet day does not mark a bottom. A real reversal would need bitcoin to climb back above at least one of its averages and hold there.</p>
<h3 id="sellers-keep-the-upper-hand-without-reaching-exhaustion">Sellers Keep the Upper Hand Without Reaching Exhaustion</h3>
<p>RSI, a 0 to 100 gauge of momentum, reads about 33 on the daily chart. That is weak territory. Sellers have pushed hard, but the reading has not dropped into the oversold zone below 30.</p>
<p>Oversold conditions often bring relief bounces as selling runs out of steam. Bitcoin is not there yet. That leaves room for more downside before buyers typically step in on exhaustion alone.</p>
<p>Other momentum gauges point the same way. The MACD, which compares short and longer price trends, remains below its signal line. In plain terms, downward momentum has not faded.</p>
<p>Trend strength readings show a trend taking shape, with sellers leading it. The move is young, and young trends tend to run further before they stall.</p>
<p>Momentum gives no sign of a turn yet, so price levels will carry more weight than headlines.</p>
<h3 id="76k-overhead-and-63k-below-frame-the-next-leg">$76K Overhead and $63K Below Frame the Next Leg</h3>
<p>On the daily chart, the nearest resistance lines up with the 200-day average. That overlap makes it the first real test for buyers. A daily close back above it would be the earliest sign that the damage is being repaired.</p>
<p>Clearing that hurdle would not end the work. The next barrier sits near $80,000, just above the 50-day line. Sellers who defended the summer range would likely wait there.</p>
<p>The downside looks thinner. Support comes in near $63,000, and the data lists no closer floor in between. If bitcoin slips, little on the chart would slow the fall.</p>
<p>A break below that floor would change the picture again. It would open a deeper leg of the drawdown and push the coin into territory with no nearby reference points. For now, price sits between these two levels, and the next decisive finish will likely set the direction.</p>
<h2 id="what-would-flip-the-next-three-days">What Would Flip the Next Three Days</h2>
<p>Each scenario carries a clear exit point.</p>
<ul>
 <li>Bullish: A daily close back above the 200-day line would hand buyers their first win and put the next barrier, just over the 50-day average, in play. The case fails if bitcoin slips back under Thursday's trading level.</li>
 <li>Bearish: A rejection at the 200-day line, with momentum still pointing down, would aim the coin toward the lower support. A finish above that same average would cancel this view.</li>
</ul>
<h2 id="the-chart-matters-more-than-the-advisory">The Chart Matters More Than the Advisory</h2>
<p>Three old bugs, all patched and never exploited, give holders no fresh reason to sell. Bitcoin's trend stays bearish until buyers reclaim the 200-day line, where the first resistance sits.</p>
