Thanks guys, that is the guidance I was needing.
Is EtherDelta the best place to get an idea of tokens' ongoing rate as well?
Or is there a better website/app?
No, etherdelta show you the price traded in its exchange only. Coinmarketcap is a better website which reflect coins/tokens price from various exchanges. From the market tab in each coin page, you are able to see the available exchanges and recent price traded.
