It is not if you work for JP Morgan it seems.
http://www.zerohedge.com/news/2017-03-01/jpmorgans-trading-desk-lost-money-just-two-days-past-4-yearsAccording to the article, JP only lost money only 2 days in the past 4 years. Does trading sound unpredictable to you now?
It is unpredictable only if you don't have enough information about what you are trading. Let's say you are trading bitcoins. Would you buy bitcoins from 1200$? If you answer "yes", based on which information? The thing is %99.99 of the btc traders don't have a slightest clue about what/why they are trading.
When you trade stocks for example; you probably have an expectation about the company based on your public or private information about the company so you short or long the stock.
When it comes to bitcoin; people only have expectations. (good or bad) And those expectations usually based on no actual information.
They got big capital, just do hedging, even got lose they can hedging back also.
Also their set loss can be longer. Portfolio big.
So it doesnt matter how many days they loss.
Small traders cant do hedging due to capital and cash flow, so more depends on winning ratio.
If u feel trading is unpredictable then dont trade.
At last, u still need do a decision as you are a trader.
I don't think you completely understand what "hedging" means. You can't hedge yourself forever if you are in a losing streak. It is a trump card which meant to be used only a few times when you really need to.
If you were to hedge yourself every time you made a trade, then why teh fuck do you even trade...
If you read the article, you will see that JP dudes have the information which you don't, that's why they are always on the right side of the trade.
It doesn't have anything to do with the capital at all.
