The rules of Binance Alpha seem to have changed in order to better reach real users.
Accordingly, the conditions to receive airdrops have been significantly reduced (below 200 points), but there is only one reward phase based on the first-come, first-served principle (FCFS).
This means that the reward each person receives will be higher, and those with multiple accounts can only use one account to compete.
Binance has been and is trying to build a fair playground and aims for a win-win-win relationship among users-exchanges-projects.
However, there are still many issues. A typical example is the DoubleZero (2Z) project, where the very few slots and unfair captcha distribution have led to many real users being unable to receive rewards.
In summary, Binance Alpha at the present time is still quite a good money-making channel.
