I haven’t heard about this earlier but after watching this u tube video, I find it very interesting and I guess this is the very bright idea of earning bitcoin, though I have read some comments abouth this bit for tip and many user has given their feedback even about bit for tip that it has very few users and very few people find it innovative but what the best thing I find about this bit for tip is that it is not a fraud scheme and it actually gives you the bitcoin when you will use it.
