I agree that listing wouldn't really be showing the value just after a week, but I also believe that listing means nothing as long as you are already listed in Binance. Robinhood is a great place and all but I do not believe that it would actually bring in anything substantial after Binance already listed it. Plus, being ranked 15th already means that they are doing as well as it could be hoped from them, I am not really expecting them to crack into top 10 and that means we are going to end up with something quite similar to this and nothing bigger.
I am not saying that it will not go up, all I am saying is that even if it does go up, it will be mainly based with the market going up as well and nothing too different from the market so they will not be ranked too much higher up, maybe just one or two spots but that's it.
The biggest reason why getting listed means nothing for the price is the fact that if you have volume then anyone would want to list you. This doesn't mean they support you or even have money in you, it just means they want to profit.
This much I can guarantee, shiba being in robinhood makes no sense to me, like it doesn't even say that shiba is decent or good or bad, it just tells me that it has volume. We have seen plenty of shitcoins that had volume of it is not a new thing neither. At the end of the day we have seen that there weren't that many people who got hyped about this because price didn't skyrocketed, which is a proof that shiba lost its hype already.
