"Learn and Earn" from the cryptocurrency exchange platform Binance, users receive rewards in different tokens after completing educational content and quizzes about projects in the crypto ecosystem. In this case, the reward was granted in EDEN currency, credited after meeting the requirements of the activity. However, although the reward was effectively received, the tokens are assigned to a locked Earn product, which implies that they remain held for a certain period and cannot be withdrawn, sold, or freely used until that period ends. During that time, the coins remain within a savings or yield generation mechanism within the platform. This situation opens a technical and ethical debate within the crypto ecosystem. From a technical perspective, the temporary locking of rewards can be interpreted as a tool to reduce immediate selling pressure, stabilize the token market, and encourage users to keep assets within the platform's financial ecosystem. Additionally, it allows funds to participate in yield generation mechanisms while remaining locked. I question whether a reward can be considered fully available when it is not under the user's immediate control. For some participants in the ecosystem, this type of mechanism functions more as a marketing strategy and token distribution, where the reward formally exists but its real availability is conditioned by previously established locking policies by the platform or by the project.
