I first started buying bitcoin when the price was around $800 and its now over $2,600 using Coinbase.
Another thing to mention is that you can buy up to $20 a week without having to provide your SS#.
Coinbase has a sign up referral link where you earn $10 worth of bitcoin and at the same time I get helped by earning $10 as well.
here's the link if anyone is interested in signing up with Coinbase
