Was there whole night the 8th, got some offer at 458 but i didn't see 3k offers at all, it's weird
Could it be someone selling to himself and some bot/guys followed the price?
when you place an order on an exchange, the offer that best matches (i.e. the 'cheapest' for you) your request gets filled, you can not choose which trader to trade with.
for example, if i want to buy a bitcoin and want to buy for say $5000, but the lowest offer is $300, it will automatically buy the $300 one. Even if someone is actually selling for $5000, it's impossible to buy the $5000 before all cheaper options are gone.
If i buy a lot of bitcoin and putting €3200 as the limit, then it would continue buying bitcoin until either 1) there are no bitcoins available for €3200 or cheaper or 2) I run out of money. whichever happens first. It will first buy the cheapest, then the second cheapest, then the third cheapest, etc. The price will rise accordingly, it will rise to the last trade made.
However due to arbitrage the price will be driven down quite quickly, as you can see.
must be an american, unaware there are other currency than dollar.
EURO motherfucker EURO, google it.
