I've been buying some on bittrex when I see it flatten out or decline slowly and then set a sell order anticipating a spike. It has worked out every time so far where the bitcoins I put in got sold at 20% increase in less than a week, as the spikes occur quite frequently.
To be honest I don't see any reason for it to go down to a one dollar peg unless the STEEM Stakeholders decides to implement reverse conversion where one can burn STEEM for SBDs, or something else to drastically increase the supply of SBDs.
Right now, there is 3,903,225 Steem Dollars in circulating supply according to coinmarketcap. That is nothing if the Steem Dollar is to serve its intended purpose as a currency fit for commerce in the STEEM ecosystem and the tokenized web with Smart Media Tokens. I'm sure it made sense back when it was created, as the market cap for cryptocurrencies was just a few billion USD and STEEM didn't have that many users yet. At a time where you only had a few web shops selling caps and T-shirts with the steem logo on it, that level of supply was probably enough.
However, with hundreds of billions entering the crypto-sphere, and STEEM being the fastest growing blockchain in terms of transactions, this is simply not enough money if each unit is valued at 1 dollar and many businesses looking to run on STEEM want to use it for commerce. So combine the limited supply with the fact that it is the single best crypto to use for e-commerce yet invented, and voila you get what we see at the moment. If you ask me, we should let the Steem Dollar be "Our Bitcoin" (or perhaps more precisely "our Litecoin" as it looks to be the more useful tool for every-day transactions). STEEM can then be our "mining rig" and DPoS token for the ecosystem while it is a currency of its own.
If the community decides to go that route, I can only see it going up. In which case I would rather be given 1000$ worth of SBDs than a 1000$ worth of Bitcoin (both at the current price) if I was not allowed to touch them for a year.
