Buy & sell WOOF (WOOF) 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.
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.
