    Frequently asked questions

    What do donations pay for?

    Hosting, data checks against the official sources, the Telegram and email reminders, and time to build new tools. The free calendar, guides and tools stay free. A donation is separate from Marlin Pro and does not unlock it.

    Is a donation an investment?

    No. A donation is a voluntary gift. It does not buy a token, a share, a return, a product or any right. Marlin does not issue a coin or a token.

    Is this a charitable donation?

    No. Marlin is an independent website run by its founder, not a charity, so a donation is a personal gift to the operator, it is not tax-deductible, and it is declared as income where the law requires. Blockchain transfers cannot be reversed, so check the amount and network before you send.

    Which network should I use?

    Use exactly the network written on the card. USDT on TRON (TRC-20) usually has the lowest fees. Sending on a different network than the one shown can lose the funds.

    Can I support Marlin without paying?

    Yes: share a guide with a trading friend, join the Telegram channel, subscribe to the weekly email, or add the free calendar widget to your site.
