Indokripto Koin Semesta is trading 7.4% down at IDR 750, with the reason unclear. - The September 28 move followed a September 25 close of IDR 810; search results surfaced no confirmed company announcement explaining the decline. - Bitcoin was down 0.61% and Ethereum 0.79% since their respective last closes, modest moves that do not clearly account for the larger drop. - Available evidence does not establish a broader-market cause.
