You are rite in here,man. greedy make us lose a lot. Why? Because we think that we will win more after that. Some people, the more greedy the are,the higher their win. Its like they got a great luck,i believe.
Being greedy is one of the most common human weaknesses.You and I are no exception.
I used to get over excited with the first or second instant payments in some btc doublers and used to loose big amounts in the past. Of course,such experiences taught me a lesson already and I am a little cautious now-a days.
