... How can you objectively make a judgement to hang on or to stop loss (which probably would look like a "run with the herd" because the herd have been leaving due the reason you are to accept). ...
... However one has to understand the risk with this method.
There are no risks on exchange rate movement, if you believe in the merit of your assets. I now explain why.
In my lesson above with the two assets Bitcoin and Peercoin, you own 10 BTC and 5000 PPC at an exchange rate of 0.002 BTC/PPC. After some time the exchange rate suddenly drops to 0.001 BTC/PPC.
a) If you believe in BTC only your wealth dropped
b) If you believe in PPC only your wealth increased
c) If you believe into BTC and PPC nothing changed
For payments there are ounces of gold and silver only, and you own 10 ounces of gold and 500 ounces of silver at an exchange rate of 0.02 gold ounce/silver ounce. After some time the exchange rate suddenly drops to 0.01 gold ounce/silver ounce.
a) If you believe in gold only your wealth dropped
b) If you believe in silver only your wealth increased
c) If you believe into gold and silver nothing changed
For savings you own 1000 USD and 100 shares from the Intel company at an exchange rate of 10 USD/Intel share. After some time the exchange rate suddenly drops to 5 Intel share/USD.
a) If you believe in USD only your wealth dropped
b) If you believe in Intel shares only your wealth increased
c) If you believe into USD and Intel shares nothing changed
Please do not answer impulsively, take your time to think about it. This makes it absolutely unnecessary to set stop loss limits, if you believe in both assets. And you should only own valuable assets, that you really believe in.
I have read these days that the cash of Warren Buffet is 60 billion USD. A few years ago it was 40 billion USD. Probably he does not think this radically as me, but the result is the same. Take the gain of the rising company shares (distribute assets) and wait on the next crash. Bitcoin movement learnt me that downwards is as good as upwards.
