The steady procession of long-dormant Bitcoin wallets springing back to life is showing no sign of slowing, with four more ancient stashes moving a combined $161 million over the past two weeks. According to Galaxy Research's blockchain monitoring, the awakened wallets moved 1,971.03 BTC in all between Sept. 6 and Sept. 22. The largest, holding 1,260.78 BTC worth about $100.63 million, had sat untouched since July 2016, more than 10 years, potentially delivering a gain of roughly 12,122% on a cost basis near $652.
