I think yes monero is a good coin for investments I'm not day trader so this is very best for long-term investments if you hold this coin for bull market it is a good strategy to earn profits from this coin still this coin is in buying range if you check this coin market structure you can understand it some countries are against privacy coins but still this coin in top 30 places in the crypto market .
Holder or trader , it depends on your skill and time.
As trader , it needs your free time to monitor the market.
But I think holder is the best way to do, if you are busy at real life.
Monero is good investment, but beware It's privacy coin. We don't know what will happen at the future
