You should be able to setup an ethereum wallet and trade for dogecoin on Binance.us or Kraken.No Doge on Coinbase, unfortunately. Need to use a different wallet service for that.
Know anything about hardware wallets?
Hardware wallets is how I lost $20,000. Definitely possible, but I cant write a guide on that at the moment. I would need to work up something that's foolproof with backups, and it's not something I want to rush.
