Crypto mining behemoth Bitmain acquired Telescope, an open-source bitcoin cash [($BCH(https://onchainfx.com/asset/bitcoin-cash)) wallet, on Monday. The browser-based wallet was launched earlier this year in an effort to enable instant bitcoin cash transactions. Supported by BitPay and moneybutton.com, the wallet stores cryptographic keys within a browser extension, meaning transactions are signed by the user's browser directly. The project says that storing funds in this way offers users similar security to standalone wallets.
