Diversify your portfolio from all sectors
Do not focus on one sector and bet on its growth
Diversity gives you the opportunity that one sector in your portfolio may flourish and compensate for the failure of the rest of the sectors
For example, if your portfolio has
First layer
Second layer
Games
Artificial intelligence
And a sector in them has grown significantly and the rest of the sectors have failed to achieve growth, then this will not matter to you because you own all the sectors
But if you put all your money and bet on the success of one sector, then you have sentenced your portfolio to death
