If you previously made an investment in Bitcoin and you lost, it doesn't mean you should give up on Bitcoin; learn from it and re-evaluate your decision
But unfortunately, not everyone that want to become rich could understand this process that making an investment takes risk ad you may failed from the first attempt but when you realized the cause to that mistake you made, you could possibly avoid any further reoccurrence of it, many were afraid of try again because they made a wrong step on their first approach, this also is part of the reason we always encourage that we keep learning each day about bitcoin and try as much as possible to avoid making mistakes from our end, it's more better learning from other's experience than ours.
