That is just what you DON'T NEED TO DO, you need to give support from below, if you buy then you don't support the bid side and a single sell will put you 500 sats below. Good pumps are pumps coming from the bid side, never from the ask side. Put several BTCs support on the bid side and you will move up automatically.
Negative. Let's say the current top buy order is 2450.
I have a lot of coins, and i have 3 btc to dump.
I just look at the buy orders where i can dump my 3btc at once, instead of smaller orders. Even if it gives me .25 loss for example.
The support wall is the best place to dump larger amount of coins when needed.
I can eat your support wall right now if i like, making the price drop to 1600 again.
If you buy all the sell orders, they have no choice but to buy at the top buying sells.
You make the charts go up, you make it 'look' nicer for others to jump in also.
Buy support from below is good for high volume coins. Not ICB that you can takeout with 1
BTC
