Why do you think people will dump it? They just want to reserv some asset names as web domains and sell them later? So there is no real good use for RVN in the future?
It is always normal for an overbought market to be sold and then this is where you get to see a correction to some extent. The problem with a lot of people is that they tend to not understand how to allow market develop, monitor trend and movement, before either buying or selling a market.
Moreover, you have sold during the run, and you have made some profit, live with that, and do not rush into FOMO as the market is always bound to reverse in most cases to the downside, but in this case, you want to be taking a look at the price actions and if you really do not know how to take note of some of these things, I wonder why you are trading then in the first place without knowledge of what to always do.
