Steemit was my entry to the crypto world. I didn't feel like buying cryptocurrency with money that I made at my regular job so I began writing on Steemit and selling all of my SBDs on poloniex and buying Bitcoin, Ethereum, Ripple, etc. Of course I would have done just as well if I had held the SBDs and waited for the recent price rise
Much like you, my entry into cryptocurrency in an active sense has been on Steemit, in part because I just don't enjoy a ridiculous amount of risk – and that's what the entire architecture of cryptocurrency is made out of right now. It's all risk. The fact that some of it has done extremely well just means that the cards fell just so – and if we're honest, far more have failed than have succeeded, and continue to.
So by and large, myself, I'm sitting on my steem because of two major reasons: firstly, it's almost impossible to find a decent way to spend it on something I can use, and secondly – I don't really need to spend it. I can afford to sit on it. At some point, if it becomes particularly valuable beyond my dreams of avarice, and my dreams of avarice are pretty big, I can cash out the whole thing and go do something else.
Daytrading is just too much work, and I wanted to do that much work I'd go get a straight job. Stressing out over every little dip and climb in the crypto market is also too much work, and frankly that I've got other things I'd rather do with my time.
I'm not sure that cryptocurrency is going to be a huge, world shattering change, but I'm willing to sit back and watch it while it does so, if it does so.
