I have been connected to the strong current for the past few years and I have a lot of knowledge about Bitcoin but I have recently come to know about this forum. I mainly want to be experienced in the technical aspects of Bitcoin. If I want to become expert in technical and development, please help me with information on what I need to learn and how I can move forward in this regard.
If you lack technical knowledge about Bitcoin, what now makes you think you know much about Bitcoin?
Knowing how to send and receive Bitcoin or about its total supply shouldn't be considered extensive knowledge thou

The technical and development experience you're lacking is the one that makes you expert in bitcoin otherwise you're just someone with average knowledge. I can see bunch of links being shared here already to get you started and the right board to visit for technical discussions.
