The price doesn't kill anything, the lack of funds and motivation does. I have talked with many small coin founders and I mean like really less than $10k in trading volume type of really small ones and they all say the same thing, they are planning on making so much innovation and so much furthering of the technology however they lack the funds severely.

They own their own coin and prefer not to sell it but even if they wanted to sell it the volume is so low that they wouldn't be capable of selling it by a whole lot since that would ruin the prices. Some of them even tried to buy the coins back to make the price go higher and put in some faith but instead he got back a bigger sale response from people who wanted to get out higher because of the price uptick. Hence the lack of funding is the biggest reason the small coins stop mattering and go die in some crypto corner.
