Hey, thanks very much for your advice!
Unfortunately, made my very first crypto transaction today, inspired by discovering the internal market, and lost somewhere between $40 - $70 of my Steemit account (I think that different things, the internal market, my steemit wallet, steem.supply, etc. each use a differnt method of assessing value, and this has left the amount ambiguous). sigh.
Perhaps I should lurk moar.
