It's obviously good news that institutions such as this one are showing interest in bitcoin and just cryptocurrencies in general. However, it's probably not going to affect the average Joe that much, because their services are going to be tailored for the elite few percent of traders and more likely just other institutions.

Also, pretty sure that this isn't something that is yet confirmed. They are just saying that they may or probably will do this, there is no definitive ETA other than the mid-2019 rollout which is quite vague.

Anyhow, this trend of institutional investors and businesses entering bitcoin and crypto has been growing recently. This could potentially help bitcoin grow further in the next bull market, however, I don't really see it making a lasting impact honestly in the long run.
