So you think ETC and LTC are just clones,i think you are missing something here,ETC came into existence because of a hard fork in the network and LTC is the first script coin,these are not just copy coins but they are better than some of the coins in the market.
You are wrong.
LTC is just chinesse pump and dump coin. look at it history. It is just copy codes by Charlie Lee from Bitcoin Core. Thats it. Sad but true.
ETC is a result of Ethereum hardfork. ETC was abandoned by it creator Vitalic Buterin, but it was catched up by brother of Charlie, Bobby Lee. Who still continue to mine it on his mining farm. Also a lot of China miners are still mining ETC.
But ETC has no development its blockchain consist of million of garbage programs wich are not functional at all. Also do not forget that hackers still have ETC tokens.
Bitcoin BTC is the one and only payment method with huge network.
Ethereum ETH is one and only universal blokchain for decentralised application creation.
Do not be fooled by brother Lee. They laught at what they did to LTC/ETC buyers. Just sell you garbage which do not have real usage at all. As they chinesse sell garbage all over the world, sorry but it is also true just look on picture above. Make FAKE things is what Chinese do really good and they do not really worry about reputation.
KEEP CALM !AND BUY Bitcoin BTC and Ethereum ETH
