Crypto Exchange Now supports most of wallets. If your wallet address is recognized as invalid, there is always a reason:
You confused Dash (DASH) with Dashcoin DSH). These are two different coins with two different amounts.
You confused Factom (FCT) with Fantomcoin (FCN). Different currencies as well.
Typo or character missing. Make sure that the address you specify matches the actual address of your wallet.
