A big event on August 1 lies in store for Bitcoin. Reports indicate that, on this date, Bitcoin miners plan to implement a protocol upgrade proposal called BIP148 in a bid to end a stalemate among various parties regarding the block size debate – a wide-ranging debate which also includes calls to increase transactions and speed up their completion times on the network. Subsequently, transaction fees for Bitcoin are currently high amid the risk of a possible chain split or fork. A chain split, in turn, could result in Bitcoin Wallets emptying overnight on August 1 because some providers may not be on the new chain.
