surely you have experienced the worst decisions when using bitcoin?
then what was the best decision?
so far I don't have any worst decision that I make at the present time now. Because I am very thankful to the member here in bitcointalk forum. With there experience I'm aware for everything which I must not do, like investing in any kind of cloudmining site and giving a tips for not playing in any gambling sites too.
Its good to know that you have learned from this forum that what is right and what is wrong, and you invested your time in reading the experience of people to avoid losses.
