XRP is getting slaughtered on the market right now after that blow that Coinbase wasn't considering adding them... it needs to hold this support area we're at currently or its a long way down.. I predicted that Stellar Lumens may pass Ripple by the end of this year, and I still think thats entirely possible. 3$ is possible but at the moment its not looking likely or anytime soon.. XRP first needs to avoid disaster of breaking this major support level... best of luck.
Coinbase is not the only exchanges, there's a lot, right? There's no chance for Stellar Lumens to overtake Ripple's XRP before the year ends. For Stellar to do that it must first improve its current market cap of $4,218,188,731 as compared to XRP's $17,929,128,629, that's what I thought.
