We can't judge investment on the basis of profit and loss. Investment for me is like a savings, from which there is a possibility of profit or loss as I invest and finally you are able to save huge amount of bitcoins.
What would you use to rate your business annual success? Is it not the profit you have made?, so why say that investment will not be judged by profit, so actually in our Bitcoin investment profit is what explains our investment success but however the success we are talking about is not the one of short term but on the contrary I'm referring to the future profit. yes I also treat my investment as a kind of savings were I need to be investing money on my chosen time but still profit is what I will use to measure my success in the future because profit and loss are the only two elements that can interpret the ending results.
