the question you may now be asking is, how do you recognise when these whales are doing this tactic, well:
when you see a stepping stone effect on the market history of stability then temp volatility, and then stability again

controlled price within limits using wallswalls removed walls set at new level
at first i was skeptical about this whole issue of whale and walls but from your explanation i can understand the reason why sometimes we have a sudden surge in bitcoin price. this shows that it is not just all about demand and supply but an additional force by the whale implementing a wall strategy that sets a new level from the previous. from the image above i can see how bitcoin was stagnant at the level of $94k but the massive buy of the whale has created a wall that led to bitcoin surge to nearly $98k and after the wall removed it set a new level in-between $94k and $98k at around $96k. i understand better now.
from my observations the green section is where a whale releases its wall (example removes the $95k wall and puts it at $98k) it then lets other investors just go mad on a buying spree without the $95k wall holding things down.
and then when the buy minnows eat up all the orders from other sell minnows from $95k to $98k. it then puts a bottom support wall in at $96k to stop it going down too much and lock minnows into buying/selling at $96k-$98k
