Looks like Federal fund rates are going to be in uptrend (Double Bottom + Bullish Divergence in RSI), in the past from 1958 to somewhere around till 1980 SPX was in sideways move or economic decline.
Can we see something similar kind of movement in SPX? IMO yes.
So, will Bitcoin follow SPX? IMO Bitcoin also moves in sideways, or Bitcoin is risk on asset so may make lower lows.
