For me, Ripple (XRP) is never and investment option, it will always be pump and dump centralized coin. Yes, your analysis is right, Whenever XRP grows and tries to fight with ETH, investors realize ETH should be given more value and we see bulky buy orders for Eth. Right now, Eth is much bigger and well established than XRP so it will continue to maintain that position until some really worthy competitor comes into the market.
