Of course it can be 10-20x, I'd argue more than that. Why? Because its only begun to exercise its UTILITY!!! They have laid the infrastructure to actually pull off the "internet of value" where money flows as freely and cheaply the way information flows globally today. They have a fantastic team, vision and the support of global government agencies and have only begun with household name partnerships such as American Express. No other platform and team can compete and because they are solving a Quadrillion dollar problem, if they actually pull it off with only 50% of the market share of that problem at the end of the day why shouldn't they be worth $10 Trillion?? It may take 8-10 years but they are evaluated at $93B today. Notwithstanding the limitations of relying on market cap you do the math on the difference there and make up your own mind whether they are undervalued. Read this blog post and do your homework. The biggest misconception is that they are centralized. Nope, not the case at all. They started that way for improved security but have taken measure to move to being completely decentralized. Its a screaming deal at $2 because after the crypto crash in the near to mid-term future there will emerge a few titans of which Ripple will be one of them. Look at Amazon and the dotcom bubble. It was a bumpy road but they emerged as a titan. Buy XRP now and don't touch it for any reason until they are mature as a company and utility. Maybe thats 4 years or maybe its 8.
