As the market becomes more saturated more users are turning towards the top two crypto coins and those who had already invested into other altcoins have starting shifting their funds towards Bitcoin and Ethereum as other altcoins have failed to capitalize the market. If this continues then how will altcoin survive? is it just the matter of time or something which altcoins need to work on by working on the missing link.
Markets are created by two types of things. Either there are securities or their are derivatives which derive their value from underlying securities. Now, securities are based on some assets and some operations which provide return and therefore value of security is appreciated. Bitcoin is an asset due to a tremendous blockchain which has a lot of users using it as a means of payment settlement. Ethereum on the other hand handles a lot of smart contracts therefore is an asset too. Coming to the rest of altcoins, Ripple has been doing nothing except announcing it's plans, other altcoins too aren't specifically doing anything than just announcing their future ventures So I think it's the time when investors want some results from altcoins before they can go on and invest in them. This is the reason altcoin market is not working.
