This calculation is very easy to calculate but in reality we don't know whether $RAYDIUM will drop to 1 dollar and go up again to 8 dollars.
Yes, that's absolutely true. The calculation is very easy, but no one knows whether the price will rise or fall because, ultimately, this is a volatile market, and no one can accurately predict the token's trajectory. Therefore, this is not investment advice.
In my opinion, in such a situation, if you have made the decision and want to invest in RAYDIUM, the best thing to do is not to buy all of your capital at once. Instead, you can follow the DCA strategy, where you buy with a portion of your capital at each dip between $1 and $1.5. I believe you will achieve a good average price in the end.
