Steem is new in the market and currently its value in USD is oscillating between $1 to $2.2. This is what happens in the initial phase. Like see the Litecoin's graph below. It was oscillating between $1 to $4 and suddenly it went up in April and since then it is continuously making "N" in the graph and going up. Similary Steem will go up its just that we yet don't know when will that April come of steem that came for litecoin in this graph. Can anybody guess which hard fork will create that day when there will be a sudden increase in USD vs Steem? Are you investing in STEEM?
