I really do not get the understanding of some people buying altcoins. I just witnessed someone buy for 0.2 BTC at 2 satoshi and he/she directly puts up a sell order at 10 satoshi.

That buy order turned into a sell order of 1 BTC. Why the fuck would you keep the prises down like this??? I bought into this coin because I saw little to no sell walls, but now they're popping up everywhere.

If you want to sell do it at level it is being traded on!
