honest, when prices rose bitcoin, very difficult to produce 0.1 BTC per day, even with trading. many are trying to switch from trading, to gambling, but mostly it just makes them less BTC. the only way to produce 0.1 BTC every week is to have a long-term investment in altcoin, or try to trade with the more powerful.
earning 0.1 bitcoin per week is really such a big amount and i do not think that one can get it from signature campaign i think it can only be possible if you are trading alt coins.
Yes to earn that high amount from signature campaign is simply possible as no campaign will pay you that high amount even if you are a high rank holder so if you want to earn that amount then you have to take a help from trading to earn them faster.
