We are talking about Ripple here. Their total supply is more than 38 billion now. When Ripple is $ 1, the market cap will surpass $ 38 billion. Does it make sense for Ripple to pass Ethereum?
Look at the marketcap of companies like Visa etc... and you deeply know, that this makes sense like nothing else. Once Ripple impacts the global finance-industry, 38B are nuts. Even 100B are not that high to stop thinking about it.
Considering people believed was not even possible to reach this kind of prices we see today few years ago, i think i wouldnt be too surprised.
