Bitcoin, Dogecoin and Peercoin all use SHA-256 Cryptography
Litecoin uses Scrypt.
They all differ in price, total coin amount and transaction time.
Doge actually uses scrypt, and I don't really know how peercoin works but they claimed that they are hybrid.
bitcoin = first cryptocurrency
litecoin = first scryptcoin and altcoin
doge = based on a joke
peercoin = ?
Peercoin= first hybrid POW/POS coin
all 3 are innovation expect dogecoin, that was created just for fun.
Dogecoin wasn't a technical innovation but it was an innovation in terms of marketing.
So, in considering precious metals and cryptocurrency analogies, if Litecoin is the silver to Bitcoin's gold, then what is copper?
Copper is in all these different electronics, et cetera. Which altcoin gets to claim to be copper? That's my question.
Who hows what is the copper in this list. Maybe NXT or DASH or PAYCOIN or any other altcoin or something. Considering that most of new coin are pre mined look in 2 year back and find something that is for third place. If we take this list for example then is something completely different in coin list for third place.
http://www.cryptocoincharts.info/coins/infoI would have thought Dogecoin would be the coin that is most analogous to copper. For example, CLAM used the blockchains of BTC, LTC, and DOGE to distribute their coins. Dogecoin is also the coin that has seen the most mainstream exposure after Bitcoin and Litecoin. After the initial success of BitcoinDark, it was quickly followed by LitecoinDark and DogecoinDark.
Many exchanges also have DOGE markets in addition to BTC and LTC markets for trading sub-satoshi/sub-liteoshi amounts.
And before Dogecoin, PPC would probably have been the coin that was closest to having the status of copper based on its market cap and similarity to LTC/BTC.
