I think you are excused a little head of steam now and again esp. when dealing with fuckwits.
I'll be honest, I have no idea wtf Dash is doing -- I posted a tweet by Charlie Lee a few weeks back in which he basically said "shit tech, no real privacy and lots of hot air marketing - not for me" and I think that sums up my attitude too. One can only apportion so much energy to this crypto-shit, its pointless obsessing over a coin that you are not invested in either intellectually or financially. Just block it out.
But I agree with you re BTC - the cultists have had their thumb in their arses about this EFT for so long I don't think they know what to think now. I skimmed the SEC document and i can't say there's much I would disagree with. It may have first mover advantage but it (BTC) has taken so many wrong turns over the years (and lost sight of any guiding principals, if any really existed) that its difficult to see where it is headed.
An interesting figure you quote there of 80% - one thing the EFT might have done is get some new money into crypto. That would have been good for everyone. But I'd agree with you, BTC is probably going to go down before it goes up again, perhaps a slow bleed and a further influx of 'crypto is dead' trolls. #ennui

Yeah - I can't believe Dash other than a pretty smart campaign of shiny stuff and restricting supply plus walls and pumping by whales in conjunction with the central cabal, clever but it will end in tears.
The D-heads are such 'true believers' someone sent me a map of 'where to spend dash worldwide' via Polo trollbox and I checked it. In UK, all I could see was a company called 'party cakes for U' and a locksmiths in the north of England.
OK no one has real retail adoption in crypto, not even BTC to a decent extent. But really, the D-heads think it's already here.
I agree in SEC, was never convinced - I sold a lot of BTC to catch the drop and no bids were filled, which surprised me.
So - with all the potential stumbles ahead - a slide is looking likely. And this is why alts are flourishing now - no way you will get 20% in a day on BTC anytime soon, other than maybe in losses...
But at $16.80 as I type, XMR is making my day rather special - been awfully quiet and having predicted a February breakout since last autumn, I was pretty down on the price.
Now I see Monero was just getting out of bed a bit late and waiting for dash and BTC look rather toppy.
Pushing $17 now... Hoo-bloody-ray!
