Invested in LTCGear and ZeusHash. I invested over $6000 worth of bitcoin in LTCGear (most of it was reinvested earnings) and finally had to sell my account for chump change just last week. ZeusHash has had my MHS contract frozen which cost a total of about 3BTC. It's been frozen for the past 8 months and there is zero support, as well as no way for me to sell the account. Cloud mining is horrible, I tell you!
Ahh. I invested in ZeusHash too. I saw they are giving out up to 5 GH/s for free last year. Joined in and than the free GHs only lasted for a few months. The promotion was so good that I invested more Bitcoin into it. Till today, as stated before.. No ROI yet.
My worst mistake was to leave 2.5 BTC on my desktop with a miserable password protecting it! Needless to say, you can imagine what was the outcome..
I learned the hard way...
Where is your desktop located at? Your house? Office or a... library? Well, next time use online application such as
https://howsecureismypassword.net/ to check how long would people take to Brut-force your password.
oh well, I did so many bad mistakes, that I don't even know where to start, so just in names:
*BFL preorder
*BlackArrow preorder
*KNC preorder (even I received their miner, it was not smart at all)
*buying dogecoin during hype
*goxxed
*gambling
..anyway, I learned a lot here and I still like bitcoin a lot, so not big deal at all:)
What's the worst mistake you made - which one make you lose most Bitcoin?
I've made some silly trades before, panic sells as it were, in a bid to short the market.
I've been fortunate enough to make more coins through trading with luck rather than a particular knowhow or ballsy trading.
This thread reminds me that I need to sort out how I go about storing and accessing my coins :/
Yeah. Me too. I have no change to a new address - HD Wallet - soon.
