Bitcoin was on track to end the week down about 3% after another failed recovery attempt in the broader cryptocurrency market, while the S&P 500 hit a record high in the United States and the Nasdaq indices advanced. Attention is shifting to token unlocks (scheduled releases of previously restricted tokens), which can increase circulating supply and pressure altcoins when the released amount is large relative to market value. Bitcoinsistemi.com's Aug. 17-23, 2026 schedule, given in UTC+3 Turkish time, shows 17 releases ranging from $1.06 million to $21.09 million, with the largest percentage release at 21.20% of market value and several others above 10%.
