Bitcoin's Path to Mass Adoption: What Needs to Change in the Next 5 Years?

With Bitcoin’s price fluctuations and the growing debate around its scalability, many are asking: what does Bitcoin need to truly reach mass adoption in the next 5 years?

While we've seen increasing institutional interest, adoption is still far from mainstream. Do you think the next phase of Bitcoin's development should focus on improving scalability, enhancing privacy features, or something else entirely?

Also, what role do you think Layer 2 solutions (like the Lightning Network) will play in Bitcoin's future? Are they the key to solving Bitcoin's scaling issues, or will we need further breakthroughs?
