it's difficult to earn Bitcoins now, even mines which will spend a lot/.
When the price of Bitcoin is kept increasing many people will start paying the very low amount to the participants. Right now we can Bitcoin only through campaign because many investment schemes are closing their doors after attaining some amount of money.
That is the biggest upset on btc sig campaigns since their participants earning will became low and some effects of it that might those signature campaigns will be close down forever, and the worse thing will be happen are their would no campaigns will be open up due to expensive price of bitcoins.
But theirs altcoin campaign that is best alternative for us but the thing here is the payment of altcoin campaigns are not instant since we need to wait for the coin to be added on exchangers.
