Bitcoin is too big for a few "whales" to have a sizable effect on major price trends -- even if significant groups of them were somehow coordinated. This explanation is commonly used in general cryptocurrency forums and even some trading forums, but it really comes down to not understanding how markets work and trying to assign some meaning (not so different from religion). Whales are not gods.

Bitcoin is tiny as currencies go or as industries go. What is it $100 billion "market cap"?

Sure. But in such a tiny volume entity like bitcoin, any large player can easily move markets.

It doesn't even have market makers or any real rules yet.

The volume today was over $4 billion. Let's say you'd need 5% of that to move the market enough for people to take notice. (Given the large volatility, this actually seems conservative) Are you suggesting that there are people who are regularly buying and selling more than $200 million worth of cryptocurrency a day?

Blatantly false -- you clearly don't monitor crypto exchange order books full time (I do). Even most small-cap altcoins have active market makers running 24/7 for ALT/BTC, ALT/ETH and ALT/USD (where supported).

Do you know from experience? There are some extremely low market cap altcoins -- you should give it a try. I do not think manipulating markets for any length of time is as easy as sideline commenters seem to believe, and it certainly is difficult to make it profitable.

Also note that many of the highest market share Bitcoin investors were early crypto enthusiasts or wealthy venture-cap-type investors, not professional/active traders. If and when there is concerted market manipulation with hundreds of millions behind it, these early adopters are certainly taking heavy losses.

But small enough to have miner pools controlling 50% of the hash rate.

True for some altcoins, but not Bitcoin. You can see the hash rates here: https://blockchain.info/pools

And even then, most pools are largely decentralized and heterogeneous -- controversial political/technical changes by the pool owner would absolutely trigger an exodus of hashrate from the pool. (As happened during the BTC/BCH fork.)
