Sorry if my question makes no sense, I am still trying to learn more about crypto in general. Which coin is more closer to BTC in all form? LTC or Doge coin? Also is any of these project have something in common with BTC?
They are both came from BTC but Dogecoin is not directly but still they have same source code so they have similarity at some point of there code. They just varies on the supply and later on to some upgrades on there blockchain.
Litecoin is the closest to Bitcoin because it was directly fork to Bitcoin they just alter some upgrades to make there blockchain more faster since they have less transaction.
