Buying on Binance without looking at liquidity is like going to the village market and wanting to sell a washing machine in the middle of the square:
—But who is going to buy it, you fool, if here they only look for chickens! 🐔
Liquidity is that: how many people are buying and selling.
If the market has little, you get a slip (like when Paco at the bar charges you too much "because there is no change").
I already learned the hard way: if there is no volume, I don't even get close. I have enough trouble with not being accepted large bills on the bus!
