The market is quite broad and no one can control the market. In my opinion, we should not care and invest in penny stocks for a long time, everything will come to us well.
When it comes to the generalized market and decentralized market, this is certain; we all control it, but when it comes to some centralized market like ripple, I can bet that this is a highly controlled market. But unfortunately many people from this community not at all ready to understand this fact.
Now, in terms of control, this is not about someone trying to put a hold on the market, or trying to fix a particular price or something, and we all know for a decentralized market, it is something hard to achieve anyway.
On the other hand, knowing that whales most especially when a market is new, will always have an upper hand, is the reason why we see prices being manipulated but all these is something that would change over time with real life usage and this is when you will get to know what is best or what is not. Whales will lose their power over time when cryptos grow bigger then absolutely we will enter into the system of decentralization.
