lone's explanation of the cost of purchasing small amount of shares is what i have found to be true as well.

i also had NOK. (up to the day before the price drop). but sold it (and many others) at a "decent loss" to make room for pricier but sure to make profit short and long term stocks. looking forward to breaking even with my original investment in a few weeks in order confirm my ideas/lesson aggregate.

keep learning. keep saving.
