It is absolutely okay to give out Bitcoin when your main goal is to spread awareness about new technology in the most efficient way. When people obtain Bitcoin in this way, they start getting interested instantly in learning about it, its downsides and upsides, and what problems it solves for them, and they start digging into questions about wallets and security because they need to protect what suddenly came to them. It is akin to aggressive marketing, where you allow customers to try out the product to convince them it is actually good, but in the case of Bitcoin, it has no negative shade because this "product" belongs to no one specifically and is fully decentralized. Another way to promote Bitcoin in your local area is to offer it in exchange for goods and services. Many people have heard about Bitcoin but were afraid of buying it because it involves some inconveniences, such as registration on an exchange, undergoing KYC procedures, and other verifications. But when you offer it directly, they may happily accept it because they already know that Bitcoin is a better form of money. If they have never heard of Bitcoin, it is also not a problem because you as a bitcoiner can educate these people by telling them about the economic model of Bitcoin, how its supply is formed, how disinflationary it is, and how it grows in value over time as it is gradually transforming from collectible to an established store of value.
