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?
What makes you think that bitcoin will go down if there is more altcoins being released? As far as i know it all depends on the supply and demand of the market and not with the other entities. We do notice that most altcoins are just following the lead of bitcoin, if bitcoin rise most of the altcoins are rising too, that is how altcoins behaving.
IMHO with eth there is another situation more erc20 token more it cost. Because everyone needs gas for the transactions, need to buy eth to participate ICO.
