People are allowed to sell at any price of their choice at exchanges. This is collapsing some tokens value and has contributed to pump and dump.
wrong and wrong.
it is as you said a free market, people are allowed to sell at any price they want and they
chose to dump those tokens because they decided that they are not worth much and they didn't see any future for any of them.
pump and dumps is a very different thing. and it seems like nobody these days dislikes them anymore. people actually starting to love pump and dump since it can make some shitcoin they were holding worth a lot more!
This do not reflect the actual values of some of the tokens.And investors make loses.Some investors buy cheap with huge bonuses at private sales so together with some hunters contribute to low prices at exchanges. The private sales buyers are one of the major dumpers because of the huge bonuses they get.So if there are limitations on the price at exchanges, it will help.
your main problem is that you read some bullshit that these ICO advertisers told you about their token and you are now thinking they have actually been doing something real!
in reality they are all terrible and this eventuality that you are seeing was expected from them. it is not really weird to see them getting dumped like this!
