What will this mean for XRP?
JPM coin and the XRP are all the opposite of bitcoin and what we like about the new digital currency. It's another currency controlled by a group of few people (companies). Ripple has focused all it's efforts in cross border fast payment, offering an alternative to the swift system used by the banks. I don't want to focus this post on how much I don't like XRP, but rather how the new centralized JPM coin used on multi trillion dollar transaction will affect XRP. That's by far the biggest threat to XRP, more than the Bitcoin itself.
How will the banks adopt those coins?
Just JPMorgan itself does enough transactions each day ($5 trillion), and if I was a partner of JPMorgan I would have to use their service eventually. This takes out of the market a large portion of potential clients for XRP.
I'm not an expert on either cryptocurrency or banks but my guess is that this will have the following repercussions on each coin. The JPM coin will be adopted by the big banks doing multiple trillion transactions each day. The XRP will be used by the small medium banks.
Edit I found this article when the CEO of Ripple, Brad Garlinghouse responded to the JPM coin. https://cointelegraph.com/news/ripple-ceo-brad-garlinghouse-says-jpmorgan-coin-misses-the-point-of-crypto
But how will this affect XLM?
Ripple and jpm coin are quite alike
Private and stable tokens for private use any where
But xlm is a Blockchain project that enables the creation of smart contracts for public private and general usage
They do not correlate I believe
