CGB has a lot of potential, check it out
Clone of Novacoin. Why would that be legitimate/solid?
Im checking out Quark and Nxt
Nxt - Do you like 100% premine? Is one person owning the entirety of a currency something that appeals to you? Also did they fix PoS or is it forced to be centralized along with being 100% premine? Nxt is the USD of cryptocurrencies.
Quark - Clone of Bitcoin with 6 different hashing algorithms. Leads fools into believing it is ASIC proof, but really it is just temporarily a botnet-miners friend.
ANC, MEC, BTB, GRC are some good ones.
ANC - Bitcoin already can connect through Tor. Coin Control is a good idea, but it isn't a protocol modification and doesn't require a new currency.
MEC - Probably made by an art student. All that it looks like was changed was the block rewards (doubled) and a flashy website was made for it.
BTB - PPC except "super rare" (in other words the creator has no idea how economics works)
GRC - LTC except centralized. You're better off donating your processing power to BOINC and mining LTC at the same time than supporting this centralized scamcoin.
Dogecoin for sure
I feel like this coin is a satire of all the other worthless altcoins.
TL;DR: Buy coins that have actual features and aren't premined or centralized (BTC, NMC).
