Right now the price of Solana is $142.20 and I don't think the price will hit the bottom $70-$90 range. Maybe if it happens, it will not in happen in the near future. So you have to wait for so long, maybe you can change your target to other alts such as ethereum, because the price now is decreasing by 15% in this week and I'm sure the price will increase again.
Solana's current price range is generally $142 - $146 in the market, and it would take a long time for one to wait for it to go below $100 again because as fans and traders in Solana haven't lost anything and it's even started to grow again so it's a bit difficult to be under $100, so changing the target for the sake of waiting for that I think is also a better solution.
