The market is a living breathing complex system. I never use set targets for buying and selling actions. I think about the elements involved.

You should always try to catch a bottom. Wait for a down trend to slow down or wait for a massive fast dip which usually get recovered in hours if not minutes.
STEEM below $4 is a good buying signal. But keep other signals in mind too.
BTC bear drags others down. The possible end of a BTC correction is a good time.
Consider trend lines, MACD, RSI. chart patterns and if you are good at it use EW or other TA methods.
Follow the news and sentiment but never make short term bets without a major announcement of TA.
Markets can go lower or higher than you'd expect.

The last time STEEM went below $4 I bought and the bloody thing went below $3. Unfortunately I have no fiat left to invest. But $3 STEEM is pretty much a crisis investment. Just don't focus much on the number. Look at the sentiment because FUD can do some terrible things for the price.

If I had some fiat I'd try to catch an uptrend. BTC could go lower. So I won't buy yet. If everything goes up, then I'll buy into the uptrend. If things keep going down, I'd wait for $3

Great advice. What do you think, with the current market, Steem for $ 100 really?
