A number of well-paying faucets can be a good source of income in the long run as a part-time earning or for retired people. I have my own set of faucets list which are well paying and PTC sites. I also grab freebies from giveaways and from my signature campaign. All this I have mad 0.1 BTC in 2 months which is a lot in my local currency and hence I do not believe faucet are a waste of time if done in a proper manner.
You said faucets are good source of income, and after that you said you also grab free coins from giveaways and signature campaign, and with all that you had maid 0.1BTC in 2 months. Sounds like to much work 0.1BTC
Lets stick to original post, how many satoshi did you earn with only faucets without giveaways and signature campaigns? We are talking about faucets, are they worth of time, not are the faucets, giveaways and signature campaigns worth of time
0.08 from faucet,ptc
0.015 for three weeks from signature campaigns for not the current one it was an old one current one gives me 0.01/week
0.02 from primedice feedback contest giveaway
Now you are going to read this and say that I made it all up
Anyway faucets and all a part-time earning for me and as a part-time it seems pretty good. My main focus is my studies and work, I never compromise my time there.
