NVST on Coin Market Cap has since the beginning had a 24 hour stat  and prices delay so nothing was in real time like it should have been.

this was a quote from my reddit thread the other day regarding this issue:

"Aside from actual development from the NVO team, I personally have been working on a few things that should help the community, such as solving some issues with CoinMarketCap and getting Blockfolio to list NVST. Right now, all CoinMarketCap stats are delayed by 24 hours, and I have been working with them to get a new API to call from, and I believe I've gotten them everything they need to fix the issue, so we're just waiting on an update from them. Blockfolio was originally going to list NVST once they got around to adding the CounterParty DEX network to their system. However, it wasn't going to be for some time because the XCP DEX API is not convenient to work with and surprisingly the solution I came up for regarding CoinMarketCap will also work for Blockfolio. Oh how I enjoy killing two birds with one stone. Anyways, we're just waiting on the Blockfolio devs now."
