Take profit or hold?

I bought some ETH at $1,700 - nothing life changing, $5,000 - so I made a fairly decent profit. I am very tempted to sell the lot, but at second thought I wanted to just take the profit. My strategy line of thought: if ETH goes down, I’m left with the cash and possibly buy some ETH back, if it goes up, sell and make a profit again. What would you do? I don’t like the continuous stress and multiple daily chart checks but I would hate to miss the golden rush if ETH goes to $10,000. I know it will, just not exactly when, and I need some cash in 3 months…
