Don't buy few years ago 
Lost some in gambling lol
I sold everything when it was very cheap. I did not know that everything would change (((.
I have not bought bitcoin yet and I'm sorry, but it's getting hotter and more expensive every day.
My biggest mistake was not buying it long time
My worst mistake was when I trade my 0.5btc to some xpy at rate 0.01xx . At that time I thought that xpy has a great future, but I was wrong. Wanted to get some profit but in fact I lost it and finally I sold my xpy at rate 0.006xx. So i lost around 0.2x btc..
I did not invest at the rate of $ 10 for 1 bitcoin. This is a very big mistake of mine 
I'm sorry.
I'm sorry. 
Not buying it in early time, now look it's price now so hight
or now, the worst has been investing 0.02 in a HYP then the site dissapeared.
Also have lost some (but less) investing on cloud mining sites.

I have lost a lot with altcoin trading, but once you get how things work money can be made. You need a lot of luck to try to guess the right pump tho, but with patience the pumps arrive, so pick your favorite up and coming coin when its cheap as hell and wait for a pump.
Yeah same here. Lost most of my bitcoins in gambling. And that was worst feeling ever. So that day I decided that I would stay away from gambling as it is better not to go for quick money as at the end of the day it is more important that you earn with respect and with hard work. If my parents gets aware that I am into gambling then they would throw me out of the home Grin
Worst mistake was not buying more with each passing week. Im still waiting for a big correction but i guess my wait is hopeless.
I have got interested in Bitcoins in 2010 but I have then forgotten to go deeper in the issue...
Selling all my Bitcoin when the price is 2k$
i read about it 3 years ago but didnt give a damn. a bad mistake. now since 1 year active and astonished what an economy raised, how many people start companies, mine, trade, or research on more advanced blockchains. it seems to be another step for the world in the digital age. keep on surprising me bitcoin and blockchain world....
Exchanged it in a bank, don't trust them. It's better to keep them. One day, bitcoin will be used in everything to buy.
Wost mistake i did with Bitcoin is selling all of them 1 year ago.
The worst mistake i did with my Bitcoin is gambling with all my Bitcoins and lose it all.
