If you are looking to buy Binance Alpha to do the airdrop task, you can consider this Skyai, as it is the first Presale on @four_meme_. Usually, any coin that carries the title 'the first' has a high chance of success.

Additionally, to optimize alpha points, you can refer to the 5-6 points range, which I believe is the most optimal, suitable for both trading volume and transaction fees.

📷32$ Buy order → 5 points → after 15 days reach 75 points

📷64$ Buy order → 6 points → after 15 days reach 90 points

Furthermore, by combining with holding a minimum of $100, each day you will receive an additional 1 point → after 15 days an extra 15 points will be added.

In total, if you trade volume and hold $100:

📷32$ → after 15 days get 90 points

📷64$ → after 15 days get 105 points

=> In summary, it is both the cheapest cost + the most points.
