The highest level of investing is not to sell. Once you get a once-in-a-lifetime asset, you must hold on tight.

There have been countless crashes and halving events in Coca-Cola's history over the past 100 years. Selling Coca-Cola at any time would be foolish.
Of course, how do you know you're holding a stock like Coca-Cola and not PetroChina?
That depends on your skill. Maybe you bought PetroChina and mistakenly held it as if it were Coca-Cola, which is entirely your own lack of vision. Buying stocks is like buying antiques; truly good stocks are as rare as genuine antiques, all depending on your eye for them.
Ordinary people are not worthy of good stocks and good assets. When ordinary people buy top-tier assets like Moutai or Coca-Cola, they are likely to sell them too early.
Therefore, to hold onto such top-tier assets, first you must make yourself extraordinary, and your character must be worthy of them.
So, does the cryptocurrency market have such once-in-a-lifetime top assets? The first one is of course $BTC , and if you have to add another, it is $ETH .
