Which of these do you think has the potential to rise in value the most?
Personally, I feel that while we can have a lot of confidence in the success of Ripple as a business, given its connections with banks, the XRP currency isn't necessary for the success of Ripple, and furthermore its circulating supply is too high to deliver substantial growth. IOTA, on the other hand, I feel has the potential to grow exponentially.
At the moment, I would choose 100% iota, because the price for it is now much better than ripple
