> A common piece of feedback from customers is transaction fees for sending Bitcoin on Coinbase are too high.
For example, around $2.50 for a 1:1 send last week or so. This is on top of the cut they take for purchases.
Clients that implemented SegWit were able to charge much lower transaction fees (~$0.15 for confirmation in 20 minutes -- less for longer waits) for the same kind of transaction.
