Fair question for sure! :) I have bought and I have sold. I'm also pretty active in the market of cryptocurrency's and I'm riding different coins each time to make a profit.

Example: Steem has been steady at $1.30 for quite a while now. Before the first of August Bitcoin had a low of $1850 or something so I invested in Bitcoin and now it stands at $3500+. Now when that stays steady again, Im gonna buy Steem again and so forth!
