In the end, who really knows what is happening with those 15k BTC?

We have coins moving here and there, but we don't know whose they are nor where they have moved, and a lot of exchanges can handle a decent amount of volume, anyhow, without really being affected - unless there is a way to show a kind of coordinated manipulation attempt.

Even the movement and the sale of a significant quantity of Gox coins in late 2017 and a few more times in 2018 were hardly proven as contributory to any kind of meaningful long term manipulation - even though claims of such were made, and likely there is a decent incentive for some short term gains from manipulator insiders (as long as they can get away with it).


You trying to exaggerate a bunch of bullshit, ECB?  Who gives a ratt's ass about a few extra BTC dumped on the BTC market, unless you are filled with hopium that this time is going to work - to get BTC prices below $5774.
 

There are more important things going on, including various other markets (traditional markets, and a bit of an alt coin dump) going down quite simultaneously... and then a question about the extent to which BTC is going to dump as much  or hold value and perhaps even show some ability to serve as a inversely correlated investment... Let's see..... Let's see.  Interesting times, in which we live, no?  And, not just one factor (such as a relatively minuscule amount of BTC being moved from one unknown address to another unknown address).   Get real...
