in terms of profit, signature is at first spot(but you need more than one accound for serious earning), then mining with very cheap electricty and cloud with cheap maintanance and then pos coins, the one with the highest rate
all the other can give to you a nice pile of dust, or it come with a very high risk, like trading or gambling
You are really the legend of signature campaigns, so many posts, i bet you earned like 10 bitcoin from it.
Really nice advice from a pro like you!
i think they were more than 10 if we count other signature in where i partecipated
, and this only by using my main account, i never cheated with signature
the good thing about signature is that it force you to learn soemthing, by posting
but i still think that if you have good electricity mining is the way, less time consuming, and you are free to do other stuff in RL
