In my own opinion, the more altcoins and erc20 tokens being released everyday in market, the more it affects Bitcoin or even Ethereum's price to go down.Since the volume of investors should be instead investing on btc and eth are now divided to altcoins.What do you think?
Everyone will think thousands of times to invest in a new altcoin, unless he has special knowledge when predicting a potential new project. Unlike when someone looks at bitcoin and ETH they will not think long to start an investment. Bitcoin and ETH have good views when seen by everyone even every new person. I think, the decline in the price of bitcoin or ETH is not caused by what you mentioned and there is not even a relation with what you mentioned.
