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?
not like that, every investor who invests in Altcoin or ICO only aims to make a profit. if they have got it, they will return to invest in Bitcoin.
