• Changelly Is our top pick for most people, it's quick & easy and works in many countries.
• Coin Mama a well known and trusted site for buying multiple crypto currencies, and works in more countries than any of the others we've seen (other than Local Bitcoins, but that's a different type of exchange) - so it's usually the next best bet for our members - if Changelly isn't available.
• IndaCoin works in 200+ countries. And a VERY "low friction" way to buy bitcoin, in fact it's probably the fastest & easiest way to buy bitcoin...just select an amount, enter your credit card and your blockchain wallet - DONE (but you pay extra for convenience).
• Local Bitcoins a way to buy bitcoins direct from someone near you (just make sure they're trustworthy; look for at least 100 confirmed trades and good feedback), a great option for those who wish to remain anonymous.
There's probably a thousand ways you can fund your wallet - these are our top picks, and will work for 99% of our members - but if you do go looking for other options, try not to get overwhelmed out there!
