Recently into crypto currency so studying into it. So two places I found you can buy crypto currency is coinbase and coinhako. Coinbase has a lower limit you can buy but the fees they charge is lower. Coinbase has a higher limit you can buy but the fees they charge is higher. Both of them requires you to authenticate yourself with an ID before you can buy and sell. Coinbase verifies you faster than coinhako. Coinbase uses sms as 2nd factor but for coinhako you have to activate google authenticator as second factor
Risk is big but returns are big are you into it. You visitors do not need to spend a cent to support me. You can also sign up coinbase or coinhako using my affilate link to support me.
Update (thanks for the support)
