In corona Pandemic, I have no job to earn. So I am joining several campaigns from bitcointalk?
What are you doing now?
What you are doing is right, never give up on looking for income, one of which you can look for researching a campaign, whether the campaign has a good future or is it a scam. Don't be shy without a job, you can start with Bounty or mining. Look for projects that don't require you to have a mining rig that spends a lot of money.
I recommend coin mining with a blockchain based on Proof of person, proof of storage and proof of stake.
If you already have a little money, try crypto trading.
