Double means that ordering 512 is equal to ordering 1024 dollars?

A couple of days ago, the coin KMNO, which had the highest trading volume on the Solana chain, moved from the alpha market to the spot market. Yesterday, it was in a relatively chaotic situation, either with unstable trading volume or high fee losses. Today, I tested it again in the alpha market and indeed found an alternative solution.
#ALPHA
Currently, the trading volume on the ETH/Base/Sonic chains is too small to consider; they cannot bear the loss at all, and I do not recommend them. The chains to choose are BNB and Solana.
Let's first look at Solana. Currently, the highest trading volume is with MEW, but the trading volume of this coin is unstable, ranging from a few U to 200 U per minute. I tried placing an order for 60 U, but several market sell orders after buying failed, and there was no response for a long time after placing the order. Then, after a few minutes, I was informed that the order failed, but the coin was not immediately returned to the account; it took about ten minutes to come back before I could place a new order. All four consecutive orders failed until the fifth one was completed, taking over an hour. This time loss is unacceptable.
