I have just bought steem. You can see it in my wallet. It took about 24 hrs to figure it out for me. I'm a noob. It is a complicated process but once you do it a few times it will not be too hard to do....I have figured out a few things so far to watch out for. www.Bittrex.com is a well respected trading platform that trades Bitcoin for steem or SBD. Since they don't take debit cards or paypal to buy either you have to buy Bitcoin and then transfer it to Bittrex and then once their you can follow this guide https://steemit.com/bittrex/@cryptos/how-to-transfer-steem-from-bittrex-to-steemit-com

I will try my hardest to put together a complete step by step walk through but it will take some time as it is very complex.

But again once you do it once or twice you would feel comfortable doing it. Learning the terminology and finding the right websites is half of the battle. For ease of use I would suggest Coinbase for creating an account that accepts normal payments and is safe and secure. It is easy to use to buy bitcoin and they have a lot of help and faqs to get you started. The less transfers you have to make the better. So Buy Bitcoin on Coinbase. Read their how to send section https://support.coinbase.com/customer/en/portal/articles/971437-how-do-i-send-digital-currency-.

You have to make sure you click the plus sign for the currency you are wanting to deposit at bittrex...This is super important. The address for deposit is what you need at coinbase to transfer funds from coinbase to bittrex Read about bittrex bitcoin wallet and how to deposit bitcoin...https://support.bittrex.com/hc/en-us/articles/115000199631-How-do-I-deposit-coins-to-Bittrex-

Until buying steem is resolved I know it is going to be difficult for new people to buy steem or SBD.

I have written an article urge people to try and help come up with a solution. https://steemit.com/steemit/@binkley/the-death-of-steem-unless-something-is-done-fast
There is an update to steemit coming very soon. Let's hope this update helps with this.
