At the beginning of August, there is LTC halving. Does Btc and ltc move together or does ltc increase independently?
Try to consider Price Graph Coinmarketcap. They move together, in the same style. That is, they are interrelated. If BTC grows, LTC also grows. So everything depends on BTC, because Altcoin is also exchanging with BTC.
If the price of BTC rises, altcoin also benefits.That's the trend that we suppose to see, however at this stage there's only few altcoins that are rising together with BTC and that includes LTC.
This means that the trend are changing and the strong coins like LTC and BNB can go with BTC but unfortunate for the majority as they are still bearish now.
