Hey @phillytube, welcome to the Steem community. It looks like you were given 15 Steem Power when you created your account. The more Steem Power you have the more transactions you can make and the more influence you can give through your upvote.

So back to your question. How to purchase Cyrpto? This is my process.

1. Make a purchase of LiteCoin through Coinbase.com.
2. Send LiteCoin (LTC) to https://blocktrades.us so that it can be converted into Steem.
3. Powerup Steem into Steem Power.

That is a high-level overview of what I do. Let me know if you have any questions.
