Hello marcoeverard! You have a terminal spike. Thus spike will continue to lengthen into a flower spike. It will produce beautiful flowers. As long as you continue to give your Phalenopsis good culture, your plant will flourish. However after awhile, it can take an entire year, your plant will stop growing, stop producing flowers. It will eventually die.
As long as you continue to give it proper care, your plant will replace itself with basel keiki. You will start to see little leaves grow at the base of the plant. Sometimes you will get two or more.
It is a long process but eventually as the keiki continues to grow, you will get a new plant. This has happened to one of my oldest and fondest Phalaenopsis I own.
Here is a recent picture of my plant. Notice the yellow stalk? That is the remains of the mother plant. I can probably detach both keiki but I'm keeping it this way as a remembrance.
Terminal spikes usually happen as a result of trauma.
