The first time I watched this in real time, I had no idea what was happening.
Mind telling us:
-When?
-What are the coins involved?
-On what exchanges/trading platform?
Manipulations do really exist especially in altcoins and so-called low cap coins. That's already a part of the trading ecosystem and no way we can avoid it.
However, we can ride it with the proper timing and well backed-up strategy.
