So the weekly chart of BTCUSD with the 21-week moving average has been very popular, as during bull runs the price seems to bounce off this average quite often. However, something I've noticed is that if BTCUSD is in an uptrend, it has a habit of touching the upper Bollinger Band week after week. If it finally doesn't, it seems to go back down to at least test the 21-week moving average.
Not sure if the past will be repeated, but it looks like this week BTCUSD might not touch the upper Bollinger Band. If BTCUSD does not touch the upper Bollinger Band, it might be worth considering trading any non-HODL part of a BTCUSD position, to see if BTCUSD heads towards a test of the 21-week moving average. Obviously (to me) BTCUSD is bullish, so the risk is to the upside, but for the short-medium term getting back to that upper Bollinger Band is important, and if BTCUSD does not do it this week, it might be a short while. If one is looking to get in or add, might be an opportunity coming up.
