Bitcoin is going to be traded in several stock exchanges very soon. Those who believe that "sharks" or "whales" wait for the day of opening and then start buying or trading are only fooling themselves.
There seems to be some confusion about this. Bitcoin IS NOT going to be traded. Bitcoin is just going to be the underlying "asset" being traded on futures. All the trading shall be done in fiat. So, whales do not need to buy anything, as they'll open and settle the transactions is fiat.
OTOH, a price pump and then subsequent dump opens the possibility for very profitable short positions in futures. However, it only makes sense if at the time of the contract the BTC value is HIGH. So, if a manipulation is being conducted, the crash is profitable only if it happens after the futures start trading and contracts are exchanged.
But any position must have an opposing buyer. So another whale must get stinged if some whale is going to make money on shorts. Therefore, some whales may think just the opposite and open long positions. Entraping whales wanting to short with the current pump, then going for another pump.
All's swell since bitcoin markets are not regulated and price manipulation is not illegal. It is therefore hard to predict that futures will trigger the crash. It may be the opposite.
It may be the opposite indeed for another few days/weeks/months but there are too many flaws in it ... it's not different than any other Ponzi Scheme ... when people buy it not because of the technology but because of speculation then it's killing all the good thing that comes with it.
Imagine a normal local grocery shop selling goods day after day.
There are people coming in and buying goods, there are suppliers selling good and overall the owner can be pleased with the business.
The owner decides it's time to have his business listed in the stock exchange in order to attract more investors.
In the beginning it's all going well, the stock is rising steadily with some drops from to time.
But then all of a sudden, comes 1 week where the stock is rising and rising and rising and the owner has no clue where it's coming from.
It gets to a position where the value of the stock reflects a sheep of investors who simply buy and buy without knowing why.
What do you think would happen to that stock?
