Miners are moving unusually large amounts of BTC(Almost 1,500 BTC) since 2 days ago. Poolin, Slush, F2Pool, HaoBTC, etc. have taken the bitcoins out of the mining wallets for a week and sent some to the exchange.

These are also the cases that often happen and I don't think it has too much impact on Bitcoin's future price. you know, when the mining power of the machines is halved, the scarcity will increase, the demand will be higher and we will see Bitcoin break ATH soon next year. Don't be alarmed by such sell-offs, the long-term future is still very good. Very good time to invest from now on.
