If you do not plan to deeply cultivate a certain field, do not invest a penny in that field, because there is a high probability that this money will be wasted, just like every time I play at level one, it ends in a loss, and the accumulated amount is also a significant sum. The only way to avoid early losses is to find a completely trustworthy senior expert in that field to follow, without having any of your own ideas, and obediently listen to the instructions!
