Some random oil sheikh can wander along and say, "What is this Bitcoin? I think I will buy this...all of this", and up it goes.
Who is going to be stupid enough to repeat the mistake of the Hunt Brothers and end up bankrupt. High networth individuals understand that liquidity is everything. If you become 99% of the liquidity by buying too much, then you can never liquidate your holdings. Pumps are always about the whales dumping on the greater fools.
What makes a market is the averaging out effect of many holders of the asset.
The risk with a smaller cap, is that just one whale gets a margin call and has to dump at a loss. No whale makes that same mistake on buying. That margin call effect can only occur to the downside, unless you have a whale holding a whale size short position.
I grow weary of talking to people who don't have good reasoning skills.
I could similarly crush your illogic about the existence of cycles. Hey scientists recently discovered the sunspots have predictable complex cycle that has been back tested throughout all recorded history. Facts are something that seem to bother you. Oh well.
