Everyone pumping shitcoins is a bit of a concern, but there is enough money for everyone in a bull market which we have and for bear markets people prefer bit caps. I would say stagnation in technology is even more of an issue, but what do I know - I am just a geek and again this can be turned around if the community at least tries to do so. There is some evidence of that: segwit adoption is growing and coinbase is being pressured to get segwit and batching implemented, which should eliminate any queue on memory pool and reduce the fees, but again that is a bit too much to explain in a reply, so should deserve its own article.
