This could even help yfi to achieve 50k target, for sure if It list on Coinbase
I am not so sure about that, the coins only get pumped before getting listed on coinbase and after getting listed on the exchange they just loose their value in a matter of a day or so. So I assume the same is going to happen to YFI as well and we can see a good dump in price after it gets listed on coinbase.
First, don't be attracted to what happen to its price in the market. Let me share to you something, I have seen a coin listed in yobit on the first day until its first week the volume was crazy moving to that platform until it reached the higher peak price was 1.9BTC something each token, then after 1 month almost the price went down little by little until more months came up the continuously dropped until the price went down into zero satoshi and no demand now, so it can happen also to that one.
Eventually all the altcoins have a lifespan and they perform very well in the start of it and then mostly tend to die after a few months and only a handful of them survive after one year and we all know that only a fraction of these survive after lets say 5 years.
