I think using it as a store of value can be quite good.
I am more interested in making extra money to pay off student loans and only saving some. The Steem extra money really helps and I do some posting on bitcointalk on my legendary name.
Steem has a ways to go to expand into grabbing more users. A lot of people Ishow Steemit to do not like the fact they have to give a phone number and email. You can alernatively create an account by paying anonsteem service to make it, but it costs .6LTC. It is what I did.
Long term invest in BTC/Steem/ETH/LTC/XRP/XMR. Have some of each and put majority into BTC/Steem/ETH for sure :)
My best selling point so far in evangelizing is that 25 mil+ people are using Bit but it is already basically global. The potential is still through the roof. Though I am doubtful America will pick it up as soon as others. It's almost like a foreign investment with all the risk in the computer scientist's/Blockstream's? hands.
