These numbers are not borrowed from other outlets — we read them directly from 21 exchanges.
| Item | Value | How to read it |
|---|---|---|
| BTC price | $81,121 (Bitrue 81,121 · Binance 81,132 · MEXC 81,127 · Gate.io 81,128 · Upbit ₩110,841,000) | Under 0.02% between exchanges — no arbitrage gap |
| BTC 24h | +6.06% ($76,486 → $81,121) | A clear rise — a day with direction |
| BTC 24h range | $76,417 ~ $81,238 (hourly closes) | Range 6.3% — wide = a choppy day |
| ETH price | $2,618 (24h +6.93%) | moving in step with bitcoin |
| Market breadth | 238 up · 49 down (of 287) | Far more coins rose = the market moved up as a whole |
| Above the long-term trendline (EMA200) | 86 coins (43%) | about half = the long-term trend is neutral |
| Kimchi premium (USDT basis) | -0.98% (24h range -1.27% to +0.74%) | Korea is cheaper = domestic buying is not following the move |
| Kimchi premium (BTC basis) | -1.02% (Upbit ₩110,841,000 ÷ FX 1,380.50 = $80,290 vs $81,121) | the same bitcoin, priced at home vs overseas |
| USDT/KRW | 1,367 KRW (reference rate 1,380.50 KRW) | Tether trades 1.0% cheaper than the reference rate |
| Futures funding rate (BTC) | 0.0067% per 8h (Binance 0.0067% · OKX 0.01% · Gate.io 0.006%) | At the baseline = longs are not crowded |
| Measured $100 fill (Binance BTC/USDT) | $81,129 · 0% slippage ($100,000 also 0%) | fills at the quoted price — plenty of liquidity |
A funding rate at the 0.01% baseline means longs are not crowding the futures market. And a negative kimchi premium means Korean investors are not chasing the move. With far more gainers than losers, the market moved together today.
Biggest gainers and losers (24h)
We count only coins with at least $10M turnover listed on three or more exchanges (this keeps single-venue pumps and scam tokens out). Prices come from the largest venue by turnover; turnover from the largest spot venue.
Biggest gainers
| Coin | Price | 24h | Turnover (spot) |
|---|---|---|---|
| AKE (AKEDO) | $0.0213 → $0.0450 | +111.19% | $32.5M |
| F (SynFutures) | $0.00319308 → $0.005259 | +64.7% | $17.9M |
| G (Gravity) | $0.00481101 → $0.007548 | +56.89% | $61.9M |
| STRK (Starknet) | $0.0286 → $0.0436 | +52.24% | $32.6M |
| AR (Arweave) | $2.64 → $3.68 | +39.24% | $11.9M |
Biggest losers
| Coin | Price | 24h | Turnover (spot) |
|---|---|---|---|
| ONE (Harmony) | $0.00209601 → $0.0016592 | -20.84% | $29.8M |
| CROSS | $0.1721 → $0.1460 | -15.18% | $1.2M |
| COTI | $0.0249 → $0.0214 | -14.24% | $13.9M |
| BTW (Bitway) | $0.7048 → $0.6151 | -12.73% | $1.6M |
| AVA (AVA (Travala)) | $0.2588 → $0.2310 | -10.74% | $8.8M |
Where the money went (turnover far above a week ago)
- GENIUS $0.3406 (-5.86%) — spot turnover $19.6M, 8.7x a week ago
- ONE $0.0016592 (-20.84%) — spot turnover $29.8M, 8.1x a week ago
- AVA $0.2310 (-10.74%) — spot turnover $8.8M, 7.6x a week ago
If turnover jumps while the price does not, someone large may be accumulating or exiting — check the order book on the coin page.
Kimchi premium right now
The kimchi premium (the price gap between Korean and overseas exchanges) is -0.98% — 24h average -0.49%, range -1.27% to +0.74%. Korea is cheaper = domestic buying is not following the move.
Coins with the widest gaps in our latest scan (one row per coin):
- MNT premium — DigiFinex $0.5762 · Upbit $0.6255 — 8.55% apart
- G premium — OKX $0.007281 · Upbit $0.0076079 — 4.49% apart
- C premium — Bitrue $0.0732 · Bithumb $0.0753 — 2.93% apart
Read these gaps after fees, transfer time and FX. They are not an arbitrage call — they are a thermometer for which side of the market runs hotter.
Funding-rate skew (which way futures lean)
The funding rate is a fee that passes periodically between longs and shorts in perpetual futures. Positive means longs pay shorts; the further it drifts from the 0.01% baseline, the more crowded one side is.
- BTC 0.0067% per 8h (about 0.02% a day) — At the baseline = longs are not crowded
- ETH 0.01% per 8h (about 0.03% a day) — At the baseline = longs are not crowded
- LSK a lot of money is betting it falls — holding leverage costs about 7.26% a day (Bybit)
- F a lot of money is betting it falls — holding leverage costs about 6.42% a day (Bybit)
A holding cost this wide is not an income opportunity — it is a signal that one side is badly crowded. On such coins, price swings dwarf the fee.
Yesterday's main stories
1. US SEC Grants Temporary 'Innovation Exemption' for Tokenized Securities Venues
On September 17, 2026, the US Securities and Exchange Commission (SEC) approved a temporary five-year 'Innovation Exemption' for specific tokenized securities venues. This regulatory decision allows National Market System (NMS) stocks to be tokenized and traded on-chain through authorized Automated Market Makers (AMMs, which are smart contracts that enable automated trading) and liquidity pools.
Following this news, Uniswap (UNI) surged 26.7% to $8.62 and Arbitrum (ARB) jumped 27.8% to $0.21, while Bitcoin and Ethereum also rebounded past $81,000 and $2,600 respectively.
2. Bitcoin Rebounds Past $81,000 Driven by ETF Inflows and Short Squeeze
On September 17, 2026, US spot Bitcoin ETFs recorded a net inflow of $159.5 million, reversing a downward trend caused by the Federal Reserve's 0.25%p interest rate hike and the rejection of the crypto-friendly Clarity Act in the US Senate. This sudden influx of buying pressure triggered a massive short squeeze in the futures market, where 74.9% of the liquidated positions were short positions (bets that the price would fall).
As a result of these factors, Bitcoin's price rose by approximately 6% over 24 hours, breaking through the $80,000 resistance level to reach a high of $81,121.
3. Ethereum Developers Agree on Sepolia Testnet Schedule for 'Glamsterdam' Upgrade
During an All Core Developers Consensus (ACDC) meeting on September 17, 2026, Ethereum core developers finalized the schedule to deploy the upcoming 'Glamsterdam' upgrade on the Sepolia testnet (a testing environment for developers). The upgrade aims to increase the block gas limit (the maximum computational effort allowed per block) to approximately 200 million to boost throughput and lower Layer-2 fees, though developers warned of potential security risks where malicious block builders could disrupt the auction system using valueless test Ether.
Supported by the concrete upgrade roadmap and a broader market recovery, Ethereum (ETH) rose by approximately 6.9% over 24 hours to reclaim the $2,618 level.
