Should I cash in my 3x return on ZAP or HODL?

I bought around $2000 of ZAP late last month (plus a lot of BTC, ETH, LINK and Sol) on the advice of a friend.

When I made the investments – my first foray into crypto btw – I was planning on holding onto each position for at least a few years, as I know trying to time the market is a fool’s errand.

But I’m already at a big profit on my Zap and could sell it right now for 3x returns… so I’m torn if I should do that or just stick to my initial plan and HODL.

How do you know when’s the right time to sell a coin? Is hoping for more than 3x overly greedy or is that within the realms of possibility when it comes to crypto investing?
