Hi is there a good website out there that would show daily, weekly and monthly change of all cryptocurrencies for a quick overview?
I think you can use
https://coinmarketcap.com this website overview cryptos coins every weeks and it is overview of volume cryptos coins too. I use it for review volume when i will trade alt coins. Hope it will help you.
Before I trade,I also review in
https://coinmarketcap.com. As I am always on short trade, I check first the volume and its graph movement before I buy. It really helps me by giving me an idea on what currency to trade. Also, on your exchanges or trading site, you can also check the coins performance to check and compare to other trading site. That way you have the overall idea of that coin.
