What do you think should be done?
These days bitcoins are not given directly in campaign but tokens are given and very less campaign give bitcoins purely.
What would you do?campaign or trading?
Well, its not about earning the money form he bitcoin signature campaign and then investing them into the trades. You can always put your own money and still stay profited. There is no risk involved now a days after looking at the bitcoin and alt coin hypes. :-)
I am reading everywhere that people are now more interested in the USDT investment which is almost similar to USD these days. The prices are stable for that and can get you quick results really.
If you fear of loosing then you should wait for good campaigns to come and then enrol into them. But to do that you will have to keep your account clean and always online. So make sure you are following the rules here. (This was just tip)
There other ways too where you can earn bitcoins. If you can makes videos and blogs then you should checkout the bounty section where token are offered for your work and you can then trade those token with BTC easily. Little more hard work than the signature campaigns but better than nothing. :-)
