...with a warning...

On Twitter and on their official blog, Coinbase today announced the official roll-out of SegWit for Bitcoin, gradually rolling out to customers next week. This will enable lower fees and faster transactions for the most popular of all cryptocurrencies.

The blog also issues a stern warning: sending Bitcoin Cash or USDT to Bitcoin SegWit addresses will result in an unrecoverable loss of funds. The Coinbase app will remind users of this danger any time Bitcoin currencies are received via the Coinbase wallet.

Coinbase reminds readers of upcoming improvements, such as transaction batching (to send transactions more efficiently at lower cost), UTXO management (managing unspent transactions more effectively), and most importantly, implementation of the Lightning network.

SegWit adoption by Coinbase will likely spur on many competing exchanges to do the same, resulting in a network effect that will significantly boost the performance of Bitcoin as a currency.

Edit It should be noted that SegWit will also be implemented for the Litecoin currency on Coinbase.
