1k$/month its high nominal, if there is someone who knows the exact way, please share, i also want to know 
as far as I know, just doing much bounty and airdrop
Airdrop and bounty can not give you that much amount of money unless you are a translator. However, to be chosen as a translators of a project, you have to fight with 5-10 other translators. If you do not have the reputation in translating, you can not apply to the job. as far as I know, just doing much bounty and airdrop
Trading is better and it is suitable for anyone. If you want to earn about $1000 in a month with crypto, you should have about $1000 and above to start your trading carreer. The more money you have, the easier of making $1000 in trading will be. I once had $20000 and turned them into $100000 after a year. I am proud of myself about this.
You can also try to gamble if you think that you are luck enough. But if you are not luck, you will have to suffer a huge loss in this entertaining industry
