Buy & sell Carbon Protocol (SWTH) with fiat currencies (USD, CAD, AUD, EUR, GBP etc) or another coin such as BTC or ETH. Harder to use for beginners but has cheaper fees.
Carbon Protocol (SWTH) is on the Ethereum network (ERC-20) so it can be stored using any ETH compatible wallet. See below for recommended wallets.
You can store coins on exchanges after purchase but we recommend using a dedicated wallet for security and long term storage. Hardware wallets offer the most security but cost money. They are the best choice for those storing a lot of value or planning to hold long term.
