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.
If you want to get more from BTC 0.1 within a day, then the way will not give drop in income is to do an online business, because by simply doing business online will certainly be sold at any price as long as the goods are indeed necessary and indeed provide sustainable benefits. Trading, gambling, investing only gives profits in a short enough time. But if business, will always provide sustainable profits
