J'ai mal lu la question posé sur Reddit, mais au cas ou un autre repose la quesiton, à réutiliser à ce moment la.

There are so many reason explaining that.
Some people do that for, well, not manipulation, but like suggestion.

Imagine, price is at 510. You set a buy order of 10 000BTC @500.
Then price will likely go up, because imagine now a guy who want to sell @510, he see the big wall order, he can think (predict ? Mistake ?) that price won't go under 500. So he will hold and may be buy (when at the first time he wanted to sell).

For the one who want to buy, seeing a 10 000 BTC wall is reassuring, you can think that by buying a little above 500, you will likely win more than lose, because the fact that price go under the 500 is not very probable. Because "destoy" a wall is hard.

For the bot, wall are taken in count to make a trade (especially for swing trades and very short term(1h/2h/4h)).

For the casual trader. Putting a wall is a way to buy at the price that YOU think is fair for your asset/currency/pair/stock. Imagine for a month price moving between 480-580. Sometimes at 580, other at 480.
You connect on your echanges, price is at 520. But you have money, and want to buy. You will put a random price on the low limit, let's say, 480,490 may be 500 (Psychological price are rounded where bots doesn't care, usually, if you do some technical analysis, you will put more smarter you order at support and resistance seen in the past).

If fact, what you see as patterns (double bottom...) and resistances and supports themselves are the association of many many trader that have just put they little order, making a big wall at the end.
