Mine would be Market Analysis. I mean if I had the ability to analyze markets and predict successfully what is going to happen, if bitcoin is going to hit a bubble or steem price will rise until a certain time and will fall relatively faster I would grow so much faster in steemit..
I would be able to help my local community. I could give advices to newcomers here and grow enough interest so that they could do free publiciity for steem. And if I had such knowledge I wouldve become full time crypto enthusiast.. I mean who wouldn't. Blockchain is the future. And we are its pioneers.
