I'm a new person involved in bitcointalk forum, I want to make Bitcoin, the method to get Bitcoin on the internet that I have read as:
1. typing to make Bitcoin free capcha => has been very little, your computer vulnerable to viruses invade
2. Investment in the website => almost all are scams
3. gamble => this is a violation of law
Please share with me what do I do to get Bitcoin?
Based on what you're saying, you want to earn it rather than buy it (which is one of the easier ways to get Bitcoin). If you want to earn it, you can join a signature campaign on this forum or go and provide some other service like writing or coding. If you can't do that, then sell something for Bitcoin. Start a business. Any way you can earn fiat you can use to earn Bitcoin. You just have to be creative.
