I feel as though I am repeating myself:

Buy more and your cost average goes down, simple math really. If you buy at the peak of a price you are bound to take a loss, smart "investors" buy all the way down to cost/average their coins.

You buy 10K at 0.004
You need to buy 40K at 0.001 cost average becomes 0.0016. If you are trying to increase your wealth at 25% gain your sell price is now lower to attain such a gain. If you sell all 50K at 0.002 you make 25%.


Edit:
But if you only spent 1.5BTC then you probably attained ~375 FRK at 0.004 therefore you only need to spend 0.45BTC (750 FRK @ 0.0006) to get to a cost average of 0.00173333.

I am curious if you worry about the people that buy the expensive coins from you when you decide to profit from others, or if your only worry is if you lose in an investment.
