Can anyone explain aside from using DAG why RaiBlocks would be preferable over highly scalable and fast existing currencies (Ripple, Lumen, etc). This really seems like a flavor of the week coin, not saying that's a bad thing. If you can make some quick money go for it, but Im not convinced there is any real reason why this coin would prevail long term unless they start getting the level of partnerships  that some of these other coins with similar performance can achieve.
