I bought some Ripple and some other currencies a month ago. I bought a small amount of them and I kept watching the charts. Finally I decided that the amount I was purchasing was so small that I had essentially created another job for myself to monitor these currencies. The amount I had wasn't worth the time... sure it may go crazy and I may miss out on becoming a bitcoin millionaire (which I did miss out on though I had the opportunity) but "Do I really want another job?" So I sold my currency.

This means I didn't have it when it just shot up in value, but I'm okay with that as any profit I made looks pretty insignificant when divided by the number of hours I watched it. That ends up being a pretty piss poor wage.

Now if I had a decent chunk of money I was willing to risk then the payoff of such efforts might make it worth doing. A few dollars here and there for hours of work though I simply realized I had more entertaining things to do and other projects to work on. Or perhaps just write some steemit blogs instead of watching those prices. Steemit tends to pay me more than monitoring my crypto. :)
