A good place to start is by not selling lower than you bought them.
Some people on here don't seem to get that one right.
I find that to be a particularly bad piece of advice.
Yes, that is exactly what I mean. I am pretty sure that at *some* point in time, the exchange rate will come above $30
You're ignoring the fact that I may be long dead before that happens. The price *may* return to $30 at *some* point in time, but my life span is finite, and I'd rather earn some money before my 60s-70s so I can enjoy it from then on.
