For its technology and long-term investments, the steem is interesting, but for the medium and short terms, the internal currencies of the platforms such as binance or kucoin seem to be promised a rise as important as the popularity, therefore the volume, passing through these exchanges. And so the BNB and KuCoin seem to me to have a very strong margin of progress.
By the way, to watch his short term trades, I found a rather powerful scanner: https://www.cryptoview.io/app/affiliate.php?codeAffil=5a4f523ef41c4 (yes it's an affiliate code, but you save 3% using it).
Thanks to @jerrybanfield for info and long live Steemit!
