I don't know if the flactuation is going to end or not. Cryptocurrency market is volatile from the start up to these days. But there are many reasons behind this. But yeah, it could be intentional because whales who holds more of Bitcoin have control over it's price. If one of them sell their Bitcoins. It affects the whole market. That's the bad side of cryptocurrency. There's no balance. Whales can buy huge amount with no limit. Some ICOs does not set any limits for their crowdfunding. And whales grab the opportunity to buy limitless amount. That's why small investors suffer once whales sold their cryptocurrency. It should be distribute equal.
