To earn bitcoin freely, There are a lot of methods. Recently I have found a new website which is the best source to earn cryptocurrency free.
https://earningcrypto.info/It is sometimes a bad idea to go with this site such as getting free especially in bitcoin. Because sometimes it is a phishing site and scammers activities or works to cheat people. However I didn't say your shared information is just like a scam but to give us an advice that not all free is free because there's nothing free right mow except the air you breathe.
