$ZEN and $DEXE are complicated cases. Both pumped out of nowhere but neither fit in the characteristics of manipulated coins.

It's not Pump & Dump, but both have such a low liquidity compared to others that they could just keep going and recover their ATHs. It's a matter of market interest.

Zen, I'd consider $21 as a good price to buy, since it's below Fib's 50% and over a reversion Order Block. As for now, people are shorting it way more than longing.

Dexe would have its turn at $8, though I'd rather holding ZEN much more than DEXE.

Below is my analysis on Horizen.
