No such thing as free lunch and no such thing as free bitcoin. No one will give you anything for free and if you want to get some bitcoins you have to invest your time and money, no matter if you are participating in signature campaign, if you gamble, trade or something else. Even faucets are not for free.
Yeah, no one in this forum or in any other field gives you anything without doing anything. You have to do something if you want to earn anything. But there are ways which you have to find if you have in search of easy ways of earning. I think if you have experience in trading and you are a expert so, you can earn through it with less effort.
I honestly hate the word free as it will not be possible and it is highly over used just to bait people. But it is our own responsibility to be careful. As per bitcoin we need to practice for living a life ttrustless. Because we should not believe into one person just for getting something for free.
