I remember before when there was a person who are selling bitcoins for a very low price I do not know why he was selling it to me but I refused not to buy it because I dont even knew it way back then. And my friends also telling me all about this stuff that they saw in the deep web but I didn't hesitate to gave an attention to it because I do not even know that I can gain money in this I thought this was just kind of new currency but a year after when my friends start gaining bitcoins I also ask them how to be involved and then I realizedbthat if I just bought that bitcoins before I have a lot of money today for sure.
One thing i regret in bitcoin is im not believe about bitcoin so that i try to use again and i put in my brain i canot surrender again because i see my co-worker he/she get lot of money.
