BTC has been around for 8 years, Steem just over a year, it has quite a upside potential. Last time I checked, there are less than 300k registered accounts and many of those are abandoned already. There are 320 million people just in the USA.

Steemit will continuously gain 'steem' (pardon the pun) going forward as more people bail from FB and onto this platform.

I think TenX and their crypto payment app on the phone will be used by a lot of people to pay for things in public in a few years. Especially using the Steem generated from this site.
