NXT at this price. Recommended price is 3000 sats
I totally agree with the point 2 of what you suggest nxt, after having a large pump the price of nxt has fallen far down and I have speculated that this is only a temporary fold and nxt will be back at the pump.
NXT was "pumped" because of the IGNIS airdrop (IGNIS, as part of the ARDOR platform) is sort of its "successor". Now that ARDOR is launched and IGNIS have been distributed, the reason of the pump is not longer present. I am surprised that the price is still so high, so I agree - it's currently overvalued in my opinion.
I also agree about most other coins mentioned here. DGB, Verge, and BitConnect are probably the "worst of the worst"; I would also add Bitcoin Gold, ICON (another Blocknet?) and TRON (until now only a token/promise). Raiblocks, IOTA, Cardano and maybe Qtum are interesting technologically, but they're still largely unproven - so the price is somewhat inflated but they
may hold it if they're able to fix problems.
Considering the long term I think about 90% of all altcoins are grossly overvalued and will crash to less than 10% of their current value. But some will hold it or even grow.
It's a clean scam like paypal because it's not a cryptocurrency with decentralization function. Owners can block every nodes like bank.
