It's a positive change to see a large bank actually considering integration with bitcoin technology (even if it is an exchange) rather than waging war against it. I guess this will be the first of its kind, and will actually allow the bank to track transactions in bitcoin thus leaving a trail, unlike when people take out a loan to buy BTC and then default.
They have nothing to lose and everything to gain if they would just allow bitcoin to be part of them. Crypto and the new revolution, rather than waging war against it, they should embrace it and I'm sure that they will gain a lot money by having its own trading desk where most of their clients can do crypto currency trades.
First it was JP Morgan, then it was Goldman Sachs, now it is Barclays. The next in what will be an ever increasing list of big financial institutions that disparage crypto before changing their mind and getting involved.
Probably more will follow and I guess we can considering this really a good news for us. Maybe around few years from now, we may see the bitcoin adoption growing to astronomical levels as this big financial institutions are all getting involved.
They have something to lose, it's just that they do not have the foresight to realize that it's inevitable. What they stand to lose is their ever increasing monopoly on online and international payments. However if they embrace Bitcoin like you said, I'm sure that in a number of years the profits they can generate from doing so will outweigh those lost by boosting the legitimacy of bitcoin as a payment option.
