Not a "necro trend", it is THE trend.
The only real way of distribution is longterm pow mining - everything else is a scam.
So longterm pow mined coins have been in accumualtion mode for quite some time and now finally broke into bullmarket.
These are the altcoins that matter, not ninjalaunch, fastmine or ico

Any new coin that wants to be a longterm project and real money token will also have to go through accumulation phase and pow mining with halvings when during early stages people will say "it's dead" while smart money buys. Sucks for you if you don't understand it.

Highly risky initial speculative bubbles are really not interesting for longterm traders. These "novelty bubbles" are only an indicator for what could come later after accumulation.
