I personally have a lot more trouble with the mid term calls than with the short term predictions. Identifying a likely developing trend, and selling or buying into it seems relatively easy for me. But the question how to take your profits, in USD or BTC, *that's* the tricky bit, imo. Park them in BTC, and you'll see your profits melt away. Park them in USD, and one swing you missed later, and you only buy 2/3 of your original coins back.
How about open a small "
hedge fond"? You stay with 50% of profit from beating the market (for example).
Not sure, but is this a test of sorts? I'm absolutely sure I'm not the only one outperforming the market (i.e. buy & hold), and pretty sure there are a lot more successful traders than me, both in percent and absolute profits. I'm doing... okay.
Anyway, I only started trading last year, and wouldn't claim I really know what's going on, and handle other people's money. Also, a very practical consideration: in an illiquid market like this, I'm already struggling with slippage at my current volume. No idea how that could be handled if managed funds are more - guess that requires a completely different type of trading strategy, that I simply have no clue about.
