Worst mistake you did with Bitcoin?

[Naitik]

Not with me, but i know my friend who made worsest mistake of his life.
About 2 years ago, he have 500 bitcoin (seriously 500 bitcoin)
but he did not have the knowledge So he made mistake he sold each coin for just 0.015$.
What a misery, now each coin worth $17k-19k.
How bad may be the things when you are running with your hard luck.

Sending BitcoinCash to a Bitcoin Segwit address...

[CryptoAdd]

Not getting involved with it earlier even though i knew about it a lot, that would be my first mistake,
my 2nd is cashing out early coz i panicked

Worst mistake I did with Bitcoin? Underestimating the power of honey badger. Evidently, HONEY BADGER DON'T CARE!

Well not bitcoin but i used to mine LTC when they where about 3-4 $ and I lost my wallet 

[Hopewell12]

because I didn't get into btc when i originally found out about it, and for not HODL when I did finally get in   

[tamsay]

losing it to ponzi schemes

My worst mistake was selling $ 10700 Bitcoin the next day. Bitcoin increased to $ 15,000 and the following day was $ 20000. That is a very unfortunate mistake for me

I always convert my coins into fiat whenever I feel I want too, never thinking that price would go high after cashing out. But now that I know it, I will now watch out and read news about bitcoin

I gave my PK to my scammer frnd..

[hicaribou]

Didnt notice it earlier.
I knew it since 2014, but didnt research it before.

[techbill]

Knowing about it, yet not spending my pay check to buy some every week.

[snkneo]

Bought it when it was over 700 usd and watched it fall all the way below 200 usd   so now I think it is no better than any other shitcoin out there.In fact some shit coins are better.

Man, this person has not been back since he posted this in August 2016. I'm sure there are many cases like his, especially with the resent pump to like $19,000.

Now his biggest mistake is not buying more for $700, then $200, and hold.

[KonstantinosM]

Kept most of my altcoins in cryptsy.

[Hemo]

Didn't buy bitcoin when the price was $6000/1bitcoin

[JbSaN]

i bought only 100 when i could buy 1000one

[Pooja Jur]

Have done some small mistakes.. all are equally worse 

[tuyulcrot]

I should have learnt to use Bitcoin before actually using them. There was a lot to know before having tried the first steps.
But I'm quite happy today, now I feel I know what I need. I keep my BTC safe, I used them when I need and I trade them every once in a while.

[lincah232]

when posting less thorough and always in a hurry so after posting a regret, it was my biggest mistake. but for now I learn more from the seniors in this bitcoin forum in order not to repeat mistakes in the post.

[yunaariska]

the worst mistake I ever committed with Bitcoin was that I once invested all my money and I suffered enormous losses back then.
but now I want to try to get back up and not repeat the same mistake.
