You can check them with statistics sites like CoinLore... Basically the site still shows positive gain values for USD, but negative values for other base currencies... There is few thousand cryptocurrencies listed on most statistics sites, so going through all of them is pointless...

My own cryptocurrency clearly follows USD.

Most go up and down with bitcoin.

I haven't tried loading all the pages to verify that, but it might well be true.... If the coin or token is worth at least 2 satoshis, then it might be traded enough against Bitcoin.
