Week after yet? SHIB is still sitting below ranking 10 coins?
https://coinmarketcap.com/currencies/shiba-inu/actually rank 15 now and still staying low after this listing

But lets see what would be the best result after a month because 1 week isn't enough to show what would be on the other side.
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.
