$SOL heavily dropped down 163.040. It is now 169.630. It's really good price to buy and hold for Spot trading.
For future trading, as it has high price than other coins. You can buy long now. However, I would expect it continue drop a little bit.
Long setup position:
Entry: 157 - 159
Target: 180 - 200 - 210
Stop loss: <= 150
Leverage: x3-x5 is recommend
Liq. price must be under 130 if you don't set stop loss
