It might inspire others and it can also help to promote your business.
0.5
BTC per month or more can possibly achievable in joining the signature campaign. The second option is you can get that profit too by doing trade in the exchange sites if you are good in prediction, or reading in the chart diagram.
it's good if you can get 0.5 of a signature campaign as it is a free and safe way. but I think this takes more time and is also a rare signature campaign that gives a high paid.
a better way can be successful and I think did it on trade. because not only get 0.5/month you can even get 1 btc more(This is my experience) and this would be my key to success to continue to trade and make a consistent profit.
