[콜드카드 코드 결함 수년간 방치... $1억 규모 BTC 해킹으로 이어져] 코인데스크에 따르면 하드웨어 지갑 콜드카드(Coldcard)의 시드문구 생성 과정에 존재했던 코드 결함이 수년간 발견되지 않으면서 약 1억 달러 규모의 BTC 탈취 사고로 이어진 것으로 나타났다. 갤럭시리서치는 약 7,300개 주소에서 1,596 BTC가 탈취된 것으로 추산했다. 문제가 된 취약점은 2021년 펌웨어 개편 과정에서 발생했다. 콜드카드는 지갑 생성 시 전용 하드웨어에서 충분한 무작위 값을 받아 시드를 생성하도록 설계됐지만, 설정 오류로 예측 가능성이 더 높은 소프트웨어 방식이 사용되면서 시드 생성에 필요한 무작위성(엔트로피)이 크게 낮아졌다. 이에 공격자가 가능한 시드 조합을 추정해 개인키에 접근할 수 있었던 것으로 분석됐다. 특히 해당 소스코드가 공개…

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate. It is computed over the 10 of 237 measured posts that carry a reaction reading, and over those same posts' views.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

Lifetime counters from Telegram’s own channel header, read 17 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. A count marked ≈ was rounded by Telegram before we ever saw it — t.me prints these counters in full below 1,000 and to three significant figures above, so ≈142,000 means somewhere between 141,500 and 142,499.
Reaction mix
6 reactions across 6 posts, in 3 distinct kinds. The most used accounts for 66.7% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| ❤ | 4 | 66.7% | |
| 👍 | 1 | 16.7% | |
| 👏 | 1 | 16.7% |
No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 10 of the 237 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 6reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 237 most recent posts we hold, published 6 August 2026 to 17 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

[BTC 공급량 45.6% 자체 보관... 거래소·수탁기관 36.1%] 자료에 따르면 비트코인 최대 공급량 2,100만개 가운데 957만 BTC(45.6%)가 자체 보관(Self-custody) 형태로 보관중인 것으로 분류됐다. 이 중 실제 자체 보관 물량은 795만 BTC(37.9%)이며, 영구 분실된 것으로 추정되는 물량은 162만 BTC(7.7%)다. 거래소 및 수탁기관이 보관하는 물량은 총 757만 BTC(36.1%)로, 거래소 291만 BTC(13.9%), 수탁기관 466만 BTC(22.2%)로 집계됐다.

[코인베이스 BTC 프리미엄, 91일 연속 마이너스...역대 최장 기간 기록] 코인글래스에 따르면 코인베이스 비트코인 프리미엄 지수는 5월 19일부터 현재까지 91일 연속 마이너스 프리미엄을 기록하고 있다. 17일 19시 30분 기준 최신 수치는 -0.1032%다. 기존 최장 마이너스 기록은 40일로, 올해 1월 16일부터 2월 24일까지 이어졌다. 코인베이스 프리미엄 지수는 코인베이스와 글로벌 거래소 간 비트코인 가격 차이를 나타내는 지표로, 마이너스가 지속되는 것은 미국 시장의 BTC 매수 수요가 글로벌 시장에 비해 상대적으로 약하다는 의미다. 크립토랭크는 "해당 지수가 다시 플러스로 전환될 경우 미국 투자자들의 자금 유입이 재개되고 있다는 초기 신호로 해석할 수 있으며, 시장 상승을 뒷받침하는 요인이 될 수 있다"고 말했다. -코인니스

🔗 Original | Author Crypto Dan 📈 View Chart "절대 바닥을 잡겠다는 생각은 틀렸다 #BTC" 절대 바닥을 잡겠다는 생각은 틀렸습니다. 약세장이 지속되면, 어느 순간 비트코인 보유자들의 평균 매입 단가가 하락하기 시작합니다. 이는 고비용 보유자들이 손실을 실현하고 더 강한 손(stronger hands)에게 코인을 이전하는 과정을 반영합니다. 이 구간에서 점진적으로 분할 매수하는 전략은 장기적으로 유리한 경향이 있습니다. 기회의 창은 대부분의 사람들이 예상하는 것보다 훨씬 오래 열려 있습니다. 그러나 바로 그 시기에 대다수는 시장을 떠납니다. ✏️ 한 줄 요약 #BTC 약세장에서 보유자 평균 매입 단가가 하락하는 구간에서 점진적 분할 매수가 장기적으로 유리하지만, 기회의 창이 예상보다 길어 대부분…

Showing the 12 most recent of 237 posts we hold for @xvgwhitedog2. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Citation-graph rank
Citation-graph rank — 386,176 of 1,481,306entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.

Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Mentions
Named by 2 registered channels — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
Names
Channels on the register whose handles appear in this channel's posts.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
