Well - the scaling debate is one of it's own, and not anything we can foresee how/if we solve, since the solution isn't come up with yet - you're trying to prove a negative, with that statement, and proving a negative, is a impossible. :)

I agree - I think you're saying basically what I am, aren't you - just without the "spend and replace" plea, which wouldn't hurt the user, but keep the network "alive" as means of exchange. That can be one of the biggest factors in driving to mass adoption.

And by no means am I saying BTC will not be replaced - but we don't know by what, and right now, we need to work with what we have - the most known and brand-valued crypto, and use that to spread adoption.

I think you're a little "glass-half-empty" on this one. Personally.

And despite having gained a decent amount on BTC growth myself, I still practice what I preach, where and when I can - use and replace.
