I do not hope this is happening but I think that it will pump but that a lot of us will not really dump it fast.
It has a good future so why would we dump it right ?
as long ethereum is alive , there will be a lot of pump and dumps happening in it. so don't worry about it and do what i do. wait for the bottom to get here after the dump has started (like right now) and buy at the bottom and dump as fast as you felt satisfied with the profit.
yes that is right it is the nature of Etherium you can really see a lot of bumps and dumps in the price of Etherium, but hope that there will no such crash that we experience in past.
Bumps and dumps are the feature and nature of not only ethereum but of a lot of other assets and currencies so it will remain there until its reach become sufficient to everyone and the etherum is now good at its work we can expect that a crash will not occur in the future in any exchange.
