But isn't it they have good fundamentals to begin with? LOL. The XRP pump has nothing to show but pure speculation. An asset with no qualitative or even quantitative values. Yeah there could be functional benefits but this pump would last long for sure.
I agree with @figmentofmyass, fundamentals is much application to altcoin specially those shitty coins out there. You really need to ask yourself a lot of questions regarding its market potential or the problems that its going to solved in real life. TA is important to coins like Bitcoin but still the overall sentiments of the market that will drove the price to go up or down.
