Since you post here in bitcointalk, signature campaign is the best way that could earn you money. Payment is greater as your rank is higher. As you get your payment, you can invest in some ICO that has a bonus rate when invested earlier. This could get you a sufficient profit but you need to wait for the ICO to end. Another is trading which you could earn a profit for just short period of time. Aside from signature campaigns, there are faucets, gambling, etc. But since you are here then give signature campaign a try.
It's not the best way to earn, but it is really good way as you don't have to do anything new like you would need to do in trading. You just have to post like you did before.
One small problem is that his account rank is still low - this might be reason why he will be too lazy to post more to earn, as it is really hard to find campaign that would pay much for low rank people, even if their posts quality is ten times better than most of Sir members.

)) You can earn very quickly if you have big capital but only try when you can accept the risk
