Cryptocurrency - Start Here steps 1 thru 3 for all - Digibyte, Bitcoin, whatever.

Step 1 - Sign up with a online Crypto wallet provider such as these guys. You can use them to buy Cryptos w credit cards etc but you will have a low limit unless u give them more info.

Step 2 - Sign up with a Crypto Exchange where u can trade 1 crypto for another crypto. You open another wallet there ( they do it automatic for u) and u can send crypto from your funding wallet like coinbase to this wallet for trading and vice versa)

step 3 - Watch youtube, read steemit, talk to people and decide what cryptos you want to buy. Like Digibyte.Then once u have a bunch u might want to save them in a wallet offline..my other posts list wallet generators online so u can print your own paper wallets
