I just started buying BTC, someone recommended me to use Bitcoin Electrum to store BTC. What is it and how do I use it?
With Electrum wallet, you can create a Standard wallet (Single signature wallet), Wallet with two-factor authentication, Multi-signature wallet, Import Bitcoin address or private keys.
Because you only start, you can use a Standard wallet. It requires only one signer (one private key) to sign your transaction.
Don't use Wallet with two-factor authentication because it will cost you more fee from Trustedcoin that is a party provides 2FA for your wallet.
If you one to have a more secure wallet, use Multi-signature wallet.
Import Bitcoin address if you want to have a Watch-only wallet. Watch-only means you can only see transactions in and out but can not sign any transaction from that wallet.
Import private keys will create a wallet that allows you to sign a transaction.
