Everyone just started to accumulate volume on the networks #Solana and #Base , as there are lower fees there, so Binance decided to introduce such a "promotion".
If you buy #Alpha tokens on the network #BSC for $128, you will be credited with a volume of $256, and the same applies to limit orders.
Keep in mind that multipliers do not multiply: if you buy the Alpha token on the BSC network with a limit order, the volume will still be x2, not x4.
