Please help me make a decision

Just when I was thinking of staking my KSMs and forgetting about them, I opened Binance, and BOOM, there it was!! I was stunned looking at the charts, as I didn’t expect it to gain any growth during this bull run. I thought Kusama was done, and I’ll sell it in the next bull market.

But now I’m confused. I don’t have any immediate expenses that would need me to take my money out, I can sit on it for another 2, or 3 years. But, should I do it? i.e. stake my coins for now and don’t take any profits in this bull run? OR should I sell my 50% of the holdings (that would give me my initial investment back along with some profits) and stake the rest of it?

Please give your suggestions and provide your opinions about what you think about the ATH of KSM in this bull run.
