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?
As newbie your only choose is altcoins,because majority of altcoins also include newbies.
and about being profitable,we cannot tell if the coin will hit big in the market or not
Just pick the best coin that you think worth your time and effort.
