The steady income here was doing trade in the exchange platform and joining in the signature campaign or buying altcoin in the ico project at the cheap price then sell it more the amount you invested.
In my view all these are are not seeming consistent.
Any type of trading will never ensure steady income. Because losses are part of trading and even professional traders are struggling for finding steady income.
Signature campaigns make give steady income, but you cannot be sure that you can be participated throughout year.
Altcoins and their ICO are very much dangerous in my eyes. One recent ICO is refusing to provide withdraw functionality for their ICO investors. They need to wait for at least two weeks for auto withdraw to happen. I guess dev will dump before their investors.
Since professional traders are always active, they can get lucky enough to buy some really good coin and never ever worry about losing money with that investment at all. Just like in ETH, if you bought months ago, right now, you don't have to think that much about the pump or dump going on because no matter what time are you selling your coins, you'd still have profit. Same with any other early investor of a coin that is booming right now (e.g. ICN, LTC). Early investors know that the price of that coin will not go back to the price that they bought it so they sell some of the coins whenever they need money and then hold the remaining for a longer time for better profit.
For signature campaign, you can always get a signature campaign if you're a constructive poster. The only ones that struggle getting in a signature campaign are those that are in the SMAS list or just plainly low quality posters. The problem is in the output that they can give for the job that they are looking for and not in the unavailability of signature campaign.
