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?
I don't know where you get that idea. Bitcoin is bitcoin and investors would love to invest their money on only the coin that is profitable at the moment. And remember that there are altcoins being born, but are you aware of many altcoins also dying and lost to oblivion?
So it doesn't makes any sense at all if you are a investor to invest on shitcoins because sooner or later they will just die and become obsolete.
