The crypto market is unfortunately bound to be under the influence of a few and of whales, partly because there is so little 'genuine' information available. When all you have to go by is the opinion of a few ' trustable' sources, they will have massive influence on prices.

To the point of the article, most of the time they'll do so to bump up price, sell off and move on. if you invest in crypto, do some research, go for the companies or people you believe in and hodl.

And remember that it is VERY risky, so don't go and borrow money for it!!!!
