do you watching the market when the pump and dump is happen? i think you missed something in the market so you loss much of money in that coins.
OP should have explained what happened in details and i hope he comes back and does that.
but here is what i have seen from these pump groups:
they advertise themselves as good and profitable, with golden signals and lots of other hyping to seem good. and then ask newbies who are desperate for earning a profit from trading to pay them some join-in fee so they can share the signals and become rich.
now what happens in reality is that the pumpers start buying some dead coin while it is still cheap and after they bought enough of it, they put up some sell orders then they call their newbies and tell them this coin is going up, and those newbies start buying those coins (mostly from those sell orders) and pushing the price up.
and when price is high enough the pumpers unload, crashing the price. now the newbies are left bag holding what they have bought from the scammer pumpers
As I got it, the OP bought some shit coin for 0.082 BTC in total and then sold it a few minutes later only for 0.014 BTC, thereby he lost roughly 90% of his investment (in Bitcoin terms). Apart from that, I don't think there are any pump groups that are deliberately buying some crap coin since they would just incur losses onto themselves
Most likely, the members of such a group are the novice traders you refer to
there are pump group but they don't buy they create fake wall i think and let the other buy, not sure how it work in details, but i'm sure that they are not so stupid to lose money when they do a pump, if there was not a pump group how do you explain all the altcoin that went crazy high in few days? it must be because of manipulation and pumpers because coins like that have no real value and usage
