If you are long term holder for bitcoin then you are smart but the market is filled with thousands of shit coins and token projects which are worthless and if you invest in those during the initial phase and did not bother to sell of when you hit the profit then you are going to be the bag holder. So where you invest makes a huge difference.
It is just them same as holding Bitcoin. If you are late to sell, you won't get anything but loss so I don't think you are smart just because you hold bitcoin for a long term. You are smart if you know when to sell and when to buy, cause the purpose of investment is to take a profit not just to see your portofolio stats increase.
And even there are many people believe Bitcoin price will go to the moon one day, it is now just speculation so it would be better if you can make money during the journey to the moon.
