"Both STEEM and SBD are extremely undervalued because they are just not available everywhere like other currencies are. "

Do you have any evidence for this wild assertion?

The problem with getting Steem listed on exchanges is obvious. It's not just a sequence of characters for an address, is it? Exchanges have to run and interface with a fucking Steemit account. There is no wallet.

Be careful what you wish for. You really want your massively-below-average-volume-for-its-market-cap, perpetually inflationary, PR-problem crypto exposed to the big boys?
