Andrew, you may not realize it, but it may be the best mistake you ever made (a blessing in disguise as they say). If Steem takes off (and I think it will), the value of Steem could rise massively in the next few months. That said, I ALWAYS transfer a very small amount when making a first transfer on any platform to make sure I understand how it works and that it does work... something you should do in future. :)
