Yes, increasing supply is useful for currencies based on most economic principles (not all). Pumps in smaller cryptocurrencies can occur due to one source, but mega caps like RIpple only pump when FOMO sets in which I believe we are seeing now. I wish they would file for an IPO - I would love to read the S1 as it would provide a lot of insight into what it takes to build a cryptocurrency the scale that Ripple is. Thanks for the valuable comment!
