Looking at the chart you posted, it more looks like $4,500 is the base of another 3x run up. Reading a chart is heavily depending on your own convictions.
But I would not recommend random people to rush into Bitcoin now because I do not know their ability to withstand possible extreme losses, both financially and emotionally.
I certainly agree and the chart is not precise to date but the big picture is the price will eventually drop. A 3:1 return with traders anticipating a drop after all time highs it is not worth the risk in my opinion. I wont be selling or trying to short the market but currently to invest more the risks for me outweigh the potential gains.
