What is happening to crypto?

I know everybody is extremely anxious about this downtrend we have been seeing in the cryptoworld, and the most worrying thing about this is that nobody seems to know why this is happening. Some of the reasons I have heard are, the coming Bitcoin fork is guilty, but the fork hasn't even happened yet, why should it take down nearly all alt-coins, come to think of it I thought these coins are decentralized, what happens to one coin shouldn't have anything to do with what happens to another.

Now I know someone will come up and explain why this is not so, but people have been explaining for a long time and never hit the button, so I'm not buying this Bitcoin is so big all other coins are subject to what happens to it.
Another theory going around is that prices in the crypto world are tied to waves and when it gets to the third or fifth or whatever wave it goes back to where it started, look this is the crypto world not the ocean where waves actually come in cycles, if this wave thing were true all these guys posting about them would be rich by now and wouldn't be posting about them.

I'll now let you know what I think, I have two ideas. One is that there are in the crypto world huge whales who put their money into all cryptos and play around increasing or decreasing prices by overselling or selling at lower prices between themselves, and in this way getting as much money as they can out of the people who when they see spikes or lows in prices buy in, I'm talking about a lot of money.

Now the second idea I have is that there are bigger players than whales involved, I'm talking about the famous .01 percent, the guys who own banks, multinationals, countries, maybe they are investing in crypto just so the wealth will not be to heavily distributed.
