1/ there is on need mainstream adoption to all get what we want here: that is moon.
2/ mainstream adoption of bitcoin by sheeples is highly unlikely anyway, they might use some top layer of it or cheap altcoins.
3/ bitcoin is no pocket money, it is a secured (by decentralized rewarded miners) safe investment haven from them FED/USG/Wall street mafia.
Bitcoin is a privilege that you'll have to pay for eventually.
else just go altcoin with max blocksize and faster transactions.
I for one firmly believe in keeping the purity of the original core. IF mainstream adoption looked more promising, then ya, something would have to give I'm afraid. One of the best things about bitcoin is the inexpensive means to send and receive. So, what do ya do?
it will never be the time for xt bs.
we need to have a core that is as 'unalienable' and 'unforkable' as possible in order to drive its price up.
not like all the current financial system, we dont want to 'QE' its blocksize or even its cap for instance. this is bad and will not drive its price up.
Bitcoin is set in stone, with small improvement that are thoroughly and minutiously investigated upstream by qualified devs.
there is no rush, there have to be a 95% consensus at least and for any major change.
bear in mind that bitcoin is no visa/mastercard/etc, it is not paypal, and this is not a race to upgrade a la Microsoft or Apple.
at some point, when/if there is a quantified demand for it, be sure 2nd layer innovations such as lightening etc will be implemented to relief bitcoin's core.
but do not touch it's very heart, that has to stay as pure and clean from all the noise large adoption would ineluctably bring.
just leave the mainstream propaganda for developing altcoins and other fake dreams.
