Hi

Welcome to Steemit :)

Nice introduction post!. To further improve on Steemit and get started, please read the following two guides that every newbie should read in order to know about different terminology used on Steemit platform or how the platform works and how to transfer your Steem that you earn from the platform to your external wallet, such as Bittrex (It's same for Poloniex as well).

The Beginner's Guide to Steemit

How to Transfer STEEM From Bittrex to Steemit

Moreover, I would also suggest to join Hive account@greetersguild, which is a community for Stemians, especially the newcomers. Here you can get different type of support from the community, including an upvote support, and of course, learning from experienced Steemians. It is created by Hive account@terminallyill, and I would like to invite you to join us :) Here is the link to our discord server. 

Oh, and you can use #greetersguild as one of your tags to get a possible upvote from Hive account@greetersguild on your quality post.

I look forward to see you there :)
