Knowledge is power and you can do better if you know the specific thing you are doing. So how about sharing knowledge?
If you share your knowledge, it does not decrease. When someone asks you a question, you just keep silent. Do you think that person will not know about that if you do not give him any information? Everything is open now. That person will know that anyway.
You do not know what would happen in the future. The person you see is not in good condition, he/she can be ahead of you in the future. Maybe you need help then. Let's help others and grow together.
there is no chance of decreasing our knowledge with sharing. it will increase increase and increase. so we should not be miser on sharing our knowledge. thanks for explaining the point nicely
And as a content creator, we are sharing our knowledge. You will never know your content can change someone's life. I'm here on blockchain based platfroms because someone shares his knowledge in his content. Thank you @engrsayful for your comment!
