In cryptotrading, a buy wall is like a giant, impenetrable fortress of bids that just won't budge - it's a massive accumulation of buy orders at a certain price level that acts as a support and prevents the price from falling further.
Buy walls are often put up by whales (large holders) or market makers who want to manipulate the price or protect their investments. They're like the bouncers at a nightclub - they decide who gets in and who gets rejected.
Example
"I was about to panic sell my Bitcoin when I saw this massive buy wall at $40K. I guess the whales still believe in the HODLing dream."
"Some whale just put up a 1000 BTC buy wall on Binance. I feel like I'm watching a real-life game of Jenga, but with money instead of wooden blocks."
