Manipulators are everywhere. They are in the stock market, they are in the hedge funds, they are in the venture capital companies, almost everywhere in the financial system. Probably they are big in numbers in the crypto market because there is no regulator, so we often fall pray to their tactics! But that's how it is and we should be accepting it the way it is. There's no way we can cut them from the system. But that doesn't make the fundamentals of bitcoin, flawed! Watch what you are saying!
Market manipulation can't be stopped only by regulations.
The market should be mature enough to become free. If we got a huge daily trading volume then it will require more money to make pumps and dumps. Now many altcoins can be pumped /dumped just by a single person trying to sell his altcoin savings.
a single person selling his altcoins is not going to dump the market even if that single person has a large amount of that coin it won't be big enough. manipulation is not just having a lot of money to dump or pump, it is about knowing how to do it in a correct way that has the most influence and can affect the price.
if it was really that easy to manipulate the price then we would have seen price of every altcoin go up and down every hour instead of what happens now which is mostly one coin getting pumped then dumped for at least 6 months before it is pumped again.
