EASY Crypto Buying/Exchange Options


1.) Easiest: Buy cryptos for USD directly inside the Exodus Wallet with credit card.

2.) Use a Swap: Send your coins to ChangeNow.io or ChangeHero.io to exchange/trade them. If possible use the fixed rate option for your first swap. It's usually faster. Watch the video tutorial below first.

Beware of Scams. Verify the Swap Address.

Slow Down. Don't Lose Your Coins.

If it is a new swap for you, exchange a small amount to test the swap before you exchange large amounts. After entering the swap, copy or take a screen shot of the swap transaction ID. If you have any concerns, send a short email including your swap transaction ID to the support address...Stuck Swap at ID [your swap id number here]...

Please watch tutorial below before your first swap. It will give you an overview of the swap process. After the swap, practice independently verifying your transaction hash and receiving address in a block explorer (see below).

You are sending one type of coin to the swap and receiving a different coin back in exchange. The basic steps in any swap are: 1.) choose your swap coins and amounts, 2.) choose options such as fixed/floating 3.) enter your PUBLIC receiving address and double check it, 4.) send coins to specified swap address, 5.) wait anywhere from 5 minutes to about 10 minutes for most coins to arrive in your wallet. *** Longer if network congestion.
