I am not sure myself as I just started, and have been trying to learn as much as possible about the platform. I bought my login details using AnonSteem which is a pretty cool service.
I've been mining and running businesses using Crypto since 2012 and I can assure you every week is a new week. I have experienced at least 3 major exchange hacks, huge swings and many other obstacles. I wouldn't be too worried about 1 week of earnings. I can only see upside with certain new currencies like Steem/ETH/DASH/ZCash etc...
I've been in cryptos since 2010 and tech since 1985 professionally. I know what you mean, but in this case, it's i feel like it is not just "market factors" affecting post values, it's steemit changes. And HF19 and rapid user growth and a lot of things... but it's a concern, as I move my software company operations towards creating more steem ecosystem apps and re-apply human resources from other client projects outside the crypto space. so what happens here, for me, is very important. Steem is something I am betting some short term company decisions on, so i need it to stabilize some.
