One year on WhatIfCoinMarketCap.com has had over 5200 submissions and growing. It has been slow organic growth as I am currently putting time into other products but overall I am happy with it.
I was not looking to monetise the service, I just released it as a free tool that might be useful for someone. I've setup a donation option if people want to buy me a coffee (with crypto) but other than that it shall remain free to use.
