There is a possibility both Zeph and Sal could be potentially rugged. Those are undergoing auditing. I would say the possibility is higher for those coins until we know the outcome.
Some coins are unlikely to be rugged. For example, doubt anyone can "rug" Bitcoin.
Salvium is practically a gamble right now... You never know when the "Audit" will be over or if it will ever be... And even if it did, the price might plummet once the transactions resume again, as many holders will be looking to sell.
Spectre is a gamble as well since the devs failed to deliver privacy in Q4 as promised, and even if they deliver, there are no guarantees that the Ghostface protocol won't have bugs like Haven.
Dero price action has been very, very disappointing recently. The coin lost more than 70% of its value in less than 3 months... I'm not fully sure if it will even cross USD 5 this bullrun.
If you look at the big picture, given the sheer number of coins in the market right now, and the fact that many institutional BTC buyers will never sell BTC for alts, gives a very dark picture for the predictions of this alt season...
I think we need to come to the realization that ALT season might not be so epic. This may be a negative idea, but let's face facts: almost every coin except the exceptional few have held onto their gains, any pumps are met with near 100% pullbacks. If your mining yield in these downturns, then we should be looking to sell on every pump and swap to BTC to hold onto that advantage. At least, this is what I'm doing now. I have a decent bag of SPR/QUBIC; everything else is getting sold on the weekly high.
