The increased traffic, number of unconfirmed transactions and the rising price all indicate to me that another pump and dump cycle is on its way. Regardless of the pump and dump, the unconfirmed transactions and slow transaction speeds are annoying me as well.
It's true that a huge transaction fees and delays are frustrating in anyways but we can't do anything about it but to wait for the network traffic to subside, and I don't really see it as an indication of a price dump instead a good sign of an economic growth in this 2 cryptocurrency, many people now are starting to invest with Bitcoin and Etherum the top 2 cryptocurrency as of this moment, and it's Christmas season now, we all know that the flow of money at this time of the year is massive.
I am also thinking that there are politics or some sort of manipulation happening inside of some cryptocurrency, group of businessman that directs to spam the network for the fees to get higher so that they can make a huge profit out of it, who knows. At the end of the day we'll still use Bitcoin and Ethereum so by any chance converting your BTC and ETH to other Altcoins that offers a very small amount of fees in withdrawing is the best move nowadays.
