I had been hodling my BTC since I bought in at $24 per back in 2013. No selling off, no weak hands. Buying in was just a very lucky move rather than any great insight.

However, six weeks ago at the beginning of November I was seduced by the talk and the prevailing sentiment of a coming "flippening" over on r/btc. Consequently, when the price of Bitcoin began to drop, I was foolish enough to believe that the r/btc guys might be correct -- that the future would be Bcash and that legacy Bitcoin was heading into a death spiral. I sold all my Bitcoin at $5,600, and bought Bcash at $2,400. Double whammied.

I have decimated my assets by a very considerable amount by listening to a bunch of shills and fools -- some of whom I now realize to have had a devious agenda. I am now preparing to sell this Bcash at $1440 and buying back into the real Bitcoin at $12,500. I cannot believe that I have been such a clown, and am feeling quite butthurt about my idiocy. I have destroyed my wealth by listening to fools.

I post this only as a cautionary tale to anyone else who might be duped and deluded by the counsel and "advice" over at that toxic dump that is r/btc.

I have not lost much, just about $200 which I lost to Ponzi scheme despite glaring signs and about $50 to an ICO. I think the experience has made my judgement better in avoiding all sorts of pump and dump strategy employed by the whales and those using ICOs to defraud people.

i guess
i made mistake,  bought my  first stellar at $69,90 usd for 100 stellar. But now  stellar in $61,77 for 100.
Because, i think it was cheapest than another coin...

I have actually lost my Bitcoin to Ponzi scheme programs,it is  very painful for losing 1 btc to a program worth not losing money for.This was out of ignorance,you can imagine what would have become of that 1 btc. Ignorance is a disease. 

Yes, I think bitcoin is not really for the poor because the money invested in it is huge. I do not think the poor enough to invest. After a recent reduction I lost a bitcoin when it dropped below 10,000 usd. That's not a small amount of money for me

I didn't lost anything yet by investing through bitcoin moreover I made my life better through bitcoin earnings.But most of the new investors(who invested in late 2017) will be suffering now due to huge price fall.So most of them were looks stupid in my view because they regret to invest on when it is available under $1000 so karma taught them a lesson.
But none of them lose their investment until they sell it,so it is better to keep your bitcoins for some months,I can assure you the bitcoin price will bump back sooner or late at the late 2018 like what happened in 2017.

I have not lost much due to stupidity, But most of my BTC goes in transaction fee from my local exchanger to foreign exchanger. It drives me Crazy!

I was offered 20 Bitcoins per month in 2011 for online reputation management of a company. The deal was for 6 months and I asked for cash. So I lost about $1200000 at current levels.

In my trading career I have lost bitcoins many times and especially it was in my starting days of trading. Sometimes it was due to ignorance or confusion and few times it was due to lack of knowledge and confidence in myself. I would like to explain in detail, at starting when I used to trade bitcoin I didn't make any trade plan nor did I make any trade journal and because of that I could not manage my trade's well and by this way, I have lost ton's of bitcoin at those starting days. Sometime's I feel lucky that I have learned to trade at those starting days because right now you can't do this mistakes and lose the same amount of bitcoins now because the BTC value is right now 100x times higher than of starting days.
