Thank you, guys.
I see only Bitquick has a purchase limit of $400 if you haven't done KYC. well, I'm not interested in that amount.

How much worth of dollars you are interested to buy the bitcoins ? By the way first you need to buy the bitcoins and later you can buy the altcoins from the exchanges.
For bitcoins or ethereum, you can buy it from
