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?
You might earn some pocket change by participating in an altcoin sigcampaign as a newbie member... The risks are:
1) the altcoin you receive turns out to be worthless
2) the OP doesn't pay up
3) the altcoin ends up to be a scamcoin
But... If the altcoin turns out to be a success, you might earn a couple satoshi's worth of altcoin, which can be exchanged for BTC or you can hodl it in the hope the price rises even further...
It's basically a gamble... If you do your homework right it might be an educated guess instead of a pure gamble... In the end there is a 99.9% probability you made less money by participating in the campaign than you would have made working at Mcdonalds... Sad but true...
If you are posting for fun instead of profit, i'd say there is little or no harm in trying.
