Seems odd that people don't understand the buy and sell wall psychology yet...
Generally:
Buy wall = someone wants to sell so they create fake confidence and sell into the fresh buy orders.
Sell wall = someone wants to buy so they create fake fear and buy the cheap coins from weak hands.
Cinni = sell walls and buy walls. It's a battle that the seller(s) is winning right now until we get some big news, then the seller will pull away (stop dumping) because they know news makes the coin worth more they can sell higher.
Pretty simple stuff...
Actually thank you for that. I wasn't entirely sure about those concepts myself. So all of those buys of like 1.0 Cinni all in a row I'm guessing are fake buy walls? So people see all of those buys and assume that it's about to take off so they start buying up the Cinni as well because they don't wanna be left behind. Then, after so many buys, the initial buyer who put up the fake buy wall dumps and makes his profit. I'm assuming that's what just happened here.
Nope
There are 2 different kinds of psychological methods to "manipulate" the market:
1) Spamming 1 Coin orders which are very near at each other (i.e. increasing the price by 1 sat per order).
This exploits the depth graph of mintpal as it only shows a specific amount of different values. If someone spams such buy orders, the graph will show only a let's say the 10 highest bids and therefore a very flat curve for buys - suggesting there are no buys at all. However, it's just a visual on the used mintpal graph software.
2) Someone place a huuge buy/sell order. As high/low so that it's just visible without scrolling, but as low/high that it doesn't get filled. This forces people to believe the coin will skyrocket/crash now and panic buy/sell. The manipulator instead places his 'real' order on the opposite, thus forcing/pulling others into their much smaller sell/buy order.
Hope it's clear
At huge pumps/dumps they readjust their big fake buy/sell orders to further support the trend.
Edit: important to mention that not each huge price development is a result of manipulation. And even if you recognize it, if it's a big one (not this twitter 20sec shit) you can still profit from it
