Yes, there are some good projects which are not in the top 50 because of their volume I guess. But looking at the volume always is not the best thing and we should be checking out the liquidity, trading patterns, price movements etc. They are not always dependent upon it neither they should be invested by looking at their volume or so on.
I am glad you have included Bancor, Dent, Bobsrepair and the last one being very new has got huge potential really. Yes, this list makes sense because there is also great potential outside top 50 box.
