Maybe with trading would have hope to earn a good income and have no binding rules.
Trading is the most used way of earning bitcoin and it's also going to give you a steady income if you do it on a daily basis. It is steady in a way that you can have daily profit but not all the time, you can earn the same amount. Because sometimes there are downs and ups and the market is always volatile so it's steady but in a different way.
It will really depends on market, at times like this as August 1 approaching and the market were difficult to predict, trading same with investing is hard due to lower values. Though these moments were limited, still trading, investing can be a good way and campaigns for additional income.
No one really knows what's going to happen but I hope that there's no more split as the percentage of support is too high already. And if this happens the market and economy of bitcoin and alt coins as well will be back to normal. For those who are earning with trading as steady income for sure it will be a good time of harvest once it becomes successful.
