Do you have any proof people buy BTC to crash the market?

[paramind22]

I have sometimes thought the big pump of 2017 was done to crash the market.  Enemies of BTC bought a lot to be able to offer sell orders at lower and lower prices therefore helping bring the price down (with public relations hit articles) whenever they wanted.  It seems often when there is good news and it seems like BTC or an alt should go up, nothing happens.  If they are still holding a large amount, Halving might not have a huge effect on price.

I'm not prone to conspiracy theories.  Wondering if anyone has any proof this could be the case.

Every crash follows human nature. Excitement builds, slowly grows, gradually becomes a mania, then a whirlwind and then one person thinks 'wait a second, why did I pay so much for this shit?' and then everyone else rapidly realises the same thing and it collapses.

Human nature doesn't change. The idea that something of that magnitude is an artificial construct ignores the more obvious explanation. It's possible it could be ignited by artificial means but it won't get anywhere unless real people latch on to it.
