It is time to buy, honestly I already buy bitcoins on the drop lately because I trusted bitcoins and they always comes back up in a fall so why doubt them. Haven't you noticed that every fall have a huge pump? The previous segwit, the bitxoins almost falls that much ad a lot of us panic selling their coins but what happened after? They pump hige than their original price. That also happen when china banned cryptocurrency it falls and after that set up a new high record so why don't just invest in them and trust them.
