Yeah you need to hold the Smart in a wallet, but there is an online wallet you can use to get the smart rewards. I think it is a pretty good coin, I was mining it until the other day I switched my miner over to point at zclassic.
I dunno. Doge tries to moon every now and then just because it is a name people recognize. I think it is just fun to own. Wouldn't expect to make money out of it.
How does one transfer Steem to smartcash? Would I have to verify my binance account first?
Sorry for the delayed response. Got lost in the shuffle. Smart is currently available on cryptomania. Don't think it is on any of the other major exchanges but I am not to sure of that, haven't bought any in awhile.
But yeah, you would need to exchange Steem or sbd for BTC or eth and use that currency to buy Smart on an exchange. There is a strong $Smart community on Steem, so check them out for additional info
