Nothing but my own personal opinion here, but ZRX (0x) is a project that I invested in weeks ago, purely on fundamental research. One of the elements of that research that I took into consideration for many coins/tokens was possibility to be added to Coinbase. While I am no pro trader by any means, and just a small time investor, crypto hobbyist, I can finally say now that fundamental research has brought a ray of light amid the bearish darkness of market sentiment at the present time. Also I should point out that the entire time that I've held ZRX, there have been many times I was tempted to Tether when it was hitting peaks, and looking back, it's about split, where half the times, had I done so, I'd have been able to buy in lower, but the other half of the time, had I Tethered, I'd have missed out on a significant rally. Thus I'm fine with the HODL strategy for now. ZRX is already a solid project, with or without Coinbase adding it at any point, so even if Bitcoin has another dive, it should come back that much stronger on the other side. Just my 2 satoshis. Enjoy your day.
