Is there any easier way than to browse back and forth through each currency and see what it is worth? Like a page collected with several of the big sites and their current values? This is a moneymaker if you do it right, correct?
There's these two, but I don't think they show exactly what you are looking for. Coinwarz I believe shows the market that has the highest price for each coin.
http://www.coinwarz.com/cryptocurrencyhttps://coinmarketcap.com/I'd go with Coinwarz if I had to choose a database. They're very accurate and have quite a bit of data per coin, not just price/coin.
I don't know how regularly it's updated, but I'd think at most 10 minute latency. So it is a good website, and I often browse it just to see what some of the other cryptos are doing. I'm not browsing to spot potential coins to trade, just looking at trends.
