Is earning through personal work online permissible if it contains no forbidden elements, and the increase in profit depends on the increase in work?

For an investment to be valid, three conditions must be met: the investment field must be permissible, there must be an agreement on a common percentage of the profit, not of the capital, and the capital must not be guaranteed.

Upon examining the nature of this website's operations, it became clear that it falls under the category of forbidden usurious transactions. The subscriber pays money to earn more money through a game of buying trees, planting them, harvesting their leaves, and converting them into a withdrawable balance. This is not a legitimate investment because the field of profit is unknown, the capital is guaranteed, and the profit is not a common percentage of future profits but a known amount that can be calculated in advance. Scholars have unanimously agreed on the invalidity of this type of transaction.

Moreover, the website offers a 20% increase on the initial deposit within 24 hours, which makes it explicit usury from day one.

Legitimate ways of earning are in two forms: either you provide work to the website for a known amount of money (without paying subscription fees), or you pay money for investment according to the aforementioned Sharia conditions. This website is not based on either of these two legitimate forms; rather, it is based on forbidden usury. Therefore, one must avoid this usurious transaction.
