My answer may come in late but I will answer still as I would like you to here the input of some who really does know much about crypto economics. My best knowledge so far on this topic is steemit and if I am already in the world of crypto-economics then steemit made that happen. Since steemit I have found myself peering deeper into the world of crypto. As per trading or exchanges etc, my best experience so far has still been with the steemit internal market. All along, I have been hoping to raise my steem power so I can truly influence people. My steemit journey has always involved the bigger picture, thus I have created the giving factory, unmean-stweets that give encouragement in the comments and @steemgigs that is going to help us exaust fully the depth of are existing community if great minds to strengthen us and paint steemit more beautiful on the outside bring about steemit growth. This has gone along with giving out tiny steem gifts daily to highlight the giving and receiving aspect of steem technology and touching people somehow. Since I missed the chance to buy steem when it was around 0.07, I was novice and I didn't have much money, so I was hoping it will go down a bit more so I can have some more steem power but then the price rose drasticly to around 0.15 and kept staying there. So I used that time to try to grow my SBD and gradually using the internal market only, it has really grown, may be by close to 100 SBD more. I just keep it there and grow it, till I am able to use it for steem power. For my experience on the outside not much. I have read stuff and have bought small number of new coins like pivx, nem and bit share using only steem but really really small quantity. Recently, I have been reading about @vivacoin and this is a whole new learning process. I mentioned them here as they be a new school of study if you need one.
