Monero, Bytecoin, Ethereum. I tried to mine many cryptocurrencies with my gtx 1050 ti, and none have proved to be worth wasting the lifetime of what little hardware I have. This is not to say cryptocurrency mining is not profitable, but to say that with the wrong hardware, you will be wasting your time mining, and you would be better off trading in the exchanges or upgrading your hardware to try again. To anyone with weaker hardware, I encourage you to find ways to earn cryptocurrency that do not involve mining, as you can be losing money if your electricity costs more than what your computer is mining. Personally, I will be using Steemit (and possibly Dtube in the future) in order to earn cryptocurrency.
I have a great interest in where cryptocurrencies and the technology behind them will go and what they will do to our world. How will daily life change in a world of decentralization and true freedom? Will we pay for our groceries and other products using steem, or another of the non-volatile digital currencies? I believe that there is a great deal of potential for digital currencies and the underlying technologies that power them.
