When to sell Solana?

I've been following the fluctuations in the Solana market for quite some time now, and I'm at a crossroads. The price has been on a steady rise, but I'm not sure if it's sustainable. Should I hold on to it, expecting further growth? Or is it time to cash out and secure my profits? The market is volatile and unpredictable, and I don't want to miss out on a potential upswing. But at the same time, I don't want to risk losing what I've gained so far. What's your advice? When should I consider selling my Solana?
