In my mind, signature campaign is an easy way to get started and earn some coins, but most campaigns are only open to high ranked users. some campaigns however, do accept newbies, like me. and i have noticed that most of those campaigns are about a new altcoin, and pays in that certain type of altcoin, which requires me to get a wallet of theirs. Any thoughts on whether its a good idea to participate in those campaigns or potential riskes?
The only potential risk is that you lose time which can be annoying. You should look at skeletoncoin any rank can join and it is suppose to be an android gaming currency. If that happens it will be great. Otherwise it is just another failed shitcoin.
