..those factors mention on that article are somehow contributed to the price jump of bitcoin..but i think the most important factor that have contributed much in bitcoin's price hike is that the demand of invester to crave more to have a lot of bitcoins for if we will going to go back for the last five months,bitcoins price are too low and much affordable that whales and other bitcoin enthusiast have bought and invested..that's why bitcoin jump 100% on its price now..
We should also be mature enough to admit that there is more than the possibility of manipulation in the markets by Bitcoin whales or even they could be just one coordinated entity working together across many exchanges. To ensure price goes up, then crashes again and again and in an endless cycle to go up so they can make more and more. Remember how this all began in april!
