Crypto Exchange Now supports most of wallets. If your wallet address is recognized as invalid, there is always a reason: 1 You confused Dash (DASH) with Dashcoin DSH). These are two different coins with two different amounts. 2 You confused Factom (FCT) with Fantomcoin (FCN). Different currencies as well. 3 Typo or character missing. Make sure that the address you specify matches the actual address of your wallet.
