There are no "manipulators", there are simply big players who have the opportunity to influence the market, and obviously take advantage of it.
If we were able, we would do it too.
For what concerns us, we can only try to understand in which direction the "manipulator" will move the market, and go after it.
Yeah, I'm telling the same thing here. Even though there can be some price manipulations going on but they are rather local and can't affect prices significantly, let alone change the overall long-term trend. Pump&dump contrivances are common for small altcoins though, where it is easy to influence the market with a minimum of funds. With bitcoin it would be very expensive and not in the least guaranteed to succeed unless we are speaking about specific moments (so-called tipping points aka pivots) when however small disturbances can cause very dramatic and lasting changes. But these moments are rare and far in between and will happen on their own sooner or later even without a directed pull.
