Start by searching for information on Google. There are also several sharia crypto communities or associations established by different groups in your country. You can obtain sharia-based crypto by visiting a crypto exchange where the coin is listed. When Mobisaria is launched, it will be listed on a specific exchange. Look for the coin’s official website — they usually provide a whitepaper you can read, which outlines their vision and mission, including how they aim to operate as a sharia-compliant cryptocurrency.
Typically, before launching, a crypto coin will conduct an airdrop where people can earn the coin for free by completing certain tasks (play-to-airdrop). The goal is to encourage public adoption of the coin. Mobisaria is also running a play-to-airdrop campaign through a game called Indonesia Adventure, which you can play on the Telegram platform.
