it is more like inevitable than anything else!

when you create some shitcoin you are creating money for yourself. and when it is very easy to do so and you can make a lot of money out of it sometimes, there is nothing stopping you from doing it. these days with ICOs things got way easier!!!

do we need them? obviously not
are they contributing to anything? not at all
are the damaging? of course. they have filled the market and took the top ranks everywhere with their pumps.
