When you say "play with" do you mean trade it or you just want to invest in steem and hold it?
It takes some figuring out but there are quite a few posts on steemit about wallets. You can try this one to start.
You can use coinbase to buy bitcoin to convert to steem / steempower
And if you are looking to trade the steem you could do that on poloniex.
There are tonnes of resources out there, these are just a few of the basic ones.
Thank you.
Mostly, I think I'd like to invest, but I'd also like to see what I can do with it in terms of trading/buying or whatever. Something to play with over the Xmas holidays.
That's exactly what I'm looking for. It's quite a bit to digest for someone just starting out. I'll start digging in...
