Step-by-step illustrated instructions for buying Bitcoin and converting it to Steem Power. There is also a great deal (disguised as a social experiment) for those new to Coinbase (at the bottom of this post).
NOTE: Please do NOT flag me until I have had a chance to respond to any complaints by editing this. I am a newbie as well (and have unintentionally transgressed) and would appreciate a chance to correct any errors before getting hammered for them. Thank you very much.
Requirements: drivers license (or national ID card) and a credit card (step-by-step instructions for using a bank account will be posted later but most users should be able to figure it out from the credit card instructions).
Steem Power is exactly what you have vested in the Steem community. Since you can only cash-out ~1%/week, it is a great indicator of how much you care about the long-term health of the community. Therefore, your voting power in the community is directly related to your Steem Power (moderated by your reputation).
The base voting power of a typical newbie is currently about 1/5000th of a US dollar (you can check yours at http://steemdollar.com/dollar_per_vote.php). It will vary with the size of the community and the value of Steem, but currently (Aug 8, 2016) it can be estimated in USD by dividing your Steem Power by ~19,000. Dolphins and whales can immediately get on the trending lists merely by up-voting their own posts.
Equally, if not more important, is the fact that curation rewards are directly proportional to your Steem Power (as a percentage of the Steem Power of all other up-voters) heavily modified by the timeliness of your vote. If you get in early before several whales hit, you can get some serious curation rewards -- if you have the Steem Power to take advantage of it (see https://steemit.com/steem-help/@liberosist/mind-your-votes-an-investigation-and-guide-to-maximizing-your-curation-rewards). If you have very little Steem Power, you are unlikely to ever see any curation rewards.
Powering up is easy if you've been noticed and are making bank with your posts and comments. Half your rewards are already in Steem Power and you can invest the other half by converting your Steem Dollars to Steem Power via either the internal market (immediate) or conversion (has a one week delay). If you're having trouble being noticed or wish to invest more quickly, the rest of this article is for you.
Coinbase (https://www.coinbase.com/) is one of the larger, older and user-friendlier of the crypto-currency players. They also have a great deal where you can get $110 worth of bitcoin for $100 and, if you follow our instructions, up to 9 Steem Dollars.
You will see a screen like the following (Note: an invitation is necessary to get the extra $10 of BTC and I must invite you for you to get up to 9 SBD).
It's interesting to see the IDs for each country. Since passports are accepted from many countries, I'm surprised that they aren't implemented for the United States . . . .
Note that the standard credit card fee (plus a little more) is passed on to you . . . . ($3.75 of that $10 sign-up bonus is effectively lost here -- but wiring from you bank will generally cost around $15 so, unless you intend to buy more than $400, this is the better option and faster)
You can always reach this screen by clicking on Trade in the left menu.
Note: Bitcoin is slow to confirm transactions. This will take anywhere from ten minutes to over an hour.
