I save bitcoin for my current and future purpose, out of my weekly earning 20% i keep for future purpose balance i convert it to fiat currency and meet my family expenses. Now i am totally depended on the forum bitcoin income as my daily life job is not much earning for me.
If you live in developed country, the payment from signature campaign will not affect much to help your daily life cost even you are a hero member now. but if you live in developing country, that payment is pretty nice to fulfil the daily necesity. I think we better to save bitcoin for future purpose.
Well, the signature campaigns earnings are not much to cover ones need, not even in the under developed countries. They can only be used as a additional part time earnings.For me. I save my bitcoins from whatever source they come like from trading, Signature Campaigns etc. because i see the future of bitcoin very bright
