Do you know Max Keizer? Check https://www.publish0x.com/coinbuzz/he-predicts-death-altcoins-and-hard-forks-xmmode ¿Do you think quality of altcoins projects that have emerged in recent times has improved? 
the quality of new crypto projects keep decreasing from time to time that is why most of the project didn't even reach their soft cap at many occasions so we cannot say the development of the new projects increased or emerged.There may be few cryptocurrency project have real working future but it buried under lot of shit coins.
