Hey there,
It looks that the price have nicely moved along the red line scenario and deviated slightly at the end. While bitcoin shows serious moves, some alts are ranging against BTC. It is very likely that on the next major move for bitcoin we might se some dramatic changes in altcoin price.
For me, if the price closes strongly above 270 it is a good signal for buying with targets around 500-600 sats.
If it drops stroongly below 170, it is possible to go even below 100. I would not recomend selling at these levels because the bottom might be close..
However, if we do see a downward continuation, I would consider a long term buy below 100.
