because people usually want to be there if a pump happens. so they try to jump on the boat which only happens if they bet more than the buywall is at.( in this case 1 guy on higher level than the wall of 8.4
secon reason is that the buywall can absorb minor sell-orders. (compare the sellorders, which are small with the buyorder, which is bigger)
1. sry im not native english
2. this is not a sure-thing... just an indicator
Edit: If there are new orders higher than buywall, the buywall will be set, if its an active pump, higher again, so that new guys order even higher... it's a circle
Thanks for the reply - who's placing these massive orders?
i rly dunno. either a person who gambles or some of the stakeholder!?
if the pump gets passive, so that just the mass of new orders(from the hype) pushes the price higher and higher, the buywallowner, which placed his wall at e.g 200 satoshi can work with a 16btc-value. so he places 8 as the wall, but the other half is already changed to earthcoin.
If the pump gets passive, it will grow higher and higher, giving him the opportunity to sell his other half at 300 satoshi.
He has to calculate that his buywall doesn't get sold(changed into earthcoin, but when it does he has to sell his other half to compensate his buy-wall-losses....
But honestly... with many btc, you can make easy more btc... you can manipulate all altcoins way to easy....
