from january 2018, bitcoin price is always changing, a suddenly increased but after a second deep dropped will surly exist. it is the vise versa of bitcoin price last year (2017). until now the price of bitcoin from january upto now (june) is still dropping. so i was wondering if theres a group of people behind this bitcoin price drop?
Not a literal manipulation but others just carried away. For example, a big whale/s can shake up a market by 10% to 15% in just single move then others will follow resulting into success triggering of that action. Include also the news associated with every dump. So overall we can't just based the price fall because of manipulation but for other factors as well.
2017 trend is a pure hype. Good thing price decrease happened in 2018 so that we can test what is the real price where support is really strong.
