I just mine altcoins that seem interessting till i have 10-100 (depends on difficulty etc.).
In this way it won't really cost me anything and i still have the profit if the coin might shoot up in value somewhere this year.
Besides that it's just fun.
How do you decide which altcoins to mine? I started with COYE, you can guess what happened...
Are there any signs i can look for, that indicate a promising altcoin, or is it just luck?
I agree in a sense its better to mine altcoins which has just been launched. More coins can be mined in the beginning; easier to mine.
And its value might just go 'to the moon'.
I have some coye as well,i guess we should have exchange or sell some in the earlier stage.
Well for the moment, i'm lookin at VERTCOIN.
