A1. Bitcoin has blockchain.info, Where can I import private keys for

- Ethereum has http://www.myetherwallet.com/, it's a website that runs on your pc, so you private keys will not touch the internet.
- Dash: you can use https://electrum-dash.org/, a local dash lite client, your private keys wont touch the internet.
- Litecoin: https://electrum-ltc.org/ same as dash electrum but for LTC.
- Monero: I don't know much about monero :/
- Dogecoin: Go here https://my.dogechain.info/#/overview and click "redeem paper wallet"
