I had some words for you friend.Bitcoin is decentralized currency,so no one will control the bitcoin price.You no need to worry for this,it's minor fluctuation.The whales can hold the price for a moment.But they can't control for longer period.This is the unique features of bitcoin over other Crypto.
I agree, it's decentralized and very hard to manipulate but whales still do it and when they do prices skyrocket or dip. Either case is a chance to make money, either by accumulating cheap BTC or by selling when reaches it's peak. Whatever the case is, BTC will exist for a long time or maybe even forever.
Yes it is true, the Bitcoins value has dropped more and more and now reached at 5.8k dollar which is a very low price and everyone can easy achieve it and is inside the circle of people.
The price may increase soon because many people will invest here in order to get Bitcoins in very large quantity and to make a collection on using low amount so this is the way they are following and you need to follow the same because everyday the market is not available like todays market.
