Because my fellow libertarians were speaking of this as the next big thing I bought $50 worth of btc when they were in the 70 cent range. I didn't think anything of it I was just supporting cause as I had many of my fellowman's causes. Being the organized person I am and not really comprehending the concept I lost the wallet most likely instantly.

While I'm certain I would have sold in the pre $100 range I still look wistfully at that illusionary $70-80,000.   

yeah gambling is a huge problem for a lot of people in a bitcoin world and it is one of the most horrible addictions in the world. My biggest mistake is that I tried doing some trading with it, it was really unsuccessful and not that I did not make any bitcoins, I actually managed to lose money with that thing.

yeah, if you want to have a lot of profit out of it you should just hold your bitcoins, but for bitcoin itself it is better that you would use it all the time.

Not just you, probably more than 50% of bitcoiners would have experience some bitter days with gambling. Some of them will mark those as their biggest mistakes. Because out of greedy no one will control themselves from gambling and thus from gambling mistakes. If we are not experienced gambling after knowing bitcoin that must be a very big achievement imho.

In near past when I just earned a few I have waste a lot of the at different sites having not enough knowledge and in search to make it more and more but this is very helpful for me and taught me a lot of things now I am pretty much experienced and have a lot of knowledge about all the sites on the internet associated with bitcoins.

There are many mistakes that I did with bitcoin in the past as when I was new to bitcoin I sent my bitcoins to wrong address and other mistake was using my bitcoins in gambling where most of the times I lost my money and loosing in gambling is still going on and god knows when I will quit gambling.

I feel what you are feel in that time since i experience too mistaken sending bitcoin to a wrong address..
But this is not the worst mistake that i made investing a large amount in ponzi is the large mistake that i made before that i thought that can brings me passive income.. but few days they turn into scam..

My biggest mistake that I have done on bitcoin is I trust someone that I really don't know who he is because he says to me that I invest on that site then you earn profit everyday forever. And because I am new in bitcoin on that day and because he is good in salestalk then he has a proof that the site is paying so I invest bitcoin then at first its paying but after a couple days it stop paying then the site is cannot open. Then the most worst is I had scammed already then I had scammed again, lost again BTC.

Me too. I was stupid and didn't know anything about Ponzi and HYIP site before, and keep deposited my money into Ponzi site for higher profit. But in the end they ran away my money and closed their service and then I stay away from HYIP.

Same with me, the first time i know bitcoin. I've been fooled by several Ponzi schemes sites like HYIP and some cloudmining that already closed.
I think things like that are commonplace for new users in the world of bitcoin because their knowledge about it. But in fact such a thing can also be avoided by actively reading the threads here. But at that time I was not familiar with bitcointalk and I think this incident is a serious error by believing hyip sites and cloudmining. Thank you

Probably the biggest mistake i have done with  Bitcoin is selling them when it was around $300.  We were about to leave bitcoin back then so we decided to sell it to buy an item and venture that small business.  We have no luck with that business so I decided to go back to Bitcoin last year. When Bitcoin start to pick up its price.  If I could turn back the time, I would have suggest to hold that BTC and wait till now to sell it if the group really wanted to  sell.
