What if I told you that it might *never* be a good unit of account, and that that wouldn't be a problem? Is gold a good unit of account? Speaking of which, is gold an invest-able asset for most people?
Fine. I am a bit tired of "whales" sinking the proverbial boat. Re gold-people could at least invest in gold ETF.
We're getting there. GBTC is on its way, and COIN will be next.
Electrum 2.0 just added Trezor support; that's just one example off the top of my head that makes things easier for me to keep my bitcoins secure but still convenient to spend. This stuff is happening incrementally. It's still very early.
