For now - let's put discussion of Nano on side bar - I literally know NOTHING about it ..... what I do know is 99% of every token coin I have ever spent over 1 day investigating has been a scam - pre-mine - shitcoin - rug pull set up . Some more blatant than others. I missed out on loads of PUMPS and therefore also the DUMPS . So I stopped looking at other shit 3-4 years ago. Been into Bitcoin since 2015 and have been HODLR thru 3 cycles .... life ( for a guy 66) is too short - I am an accountant by training and did over 20 yrs on Wall Street in emergent technology equities analysis/banking /vc. I can't comprehend 25% of the technical arguments on the intricacies of block sizes and thru puts etc etc ...If NANO is so great I'm pretty sure the best elements of it will be subsumed thru soft forks into BTC over the coming years. Best of luck with your Nano - just never going to be my shiny new object.... may be a huge mistake on my part - but I'm ok with this .

TLDR - oops - I missed the Lightning table ..... wonder why. I think I am assuming a multi layer world that is a parallel to todays physical world - Might want to read the Book Layered Money by Bhatia . Bitcoin is the ALPHA base layer protocol which is 100% optimised for security over speed -and reliability . Censorship resistance .... blah blah - the point of the book is that Bitcoin OWNS the base layer - period. Layers 2- n are a different story . I like lightning vs Liquid - but I admit I am a total noob. I need to do a lot more work on which will win and why - but all this leave me no time for Nano.
It may be the greatest thing ever - but network effect logic says it needs to be 100x better and this aint happening .

your table of comparisons is a JOKE - people I know would never buy a cup of coffee on the BTC main chain - we all use Lightning - it is virtually instant -
because of this HORRIBLE over reach - I TLDR the entire rest of your comparisons assuming each are equally inane. At least be honest with yourself - unless I am wrong and intellectual dishonesty is a virtue somehow.

Why so negative ? 'The end of what ? '

How about Buffet and Munger BRK ? - they own $33B of BAC, $22B of AXP , $2.6 B of VRSN, $2.5B of C $1.7B of V, $1.1B of BK - notably BK position was sold massively from above $7B - the only Bank on the list I am aware of who had announced an offering for customers to custody BTC at their bank. Seem like they have overweighted the "money changer" money mover element of the economy. Of course they may have intermediaries / agents helping out.

Great question -Jack ? Brian - do you mean with COIN building on top of ETH under the POS you can be a part of the committee who controls it ? Why not get serious about Lightning or Liquid sitting ontop of Bitcoin -would that not be a much more secure - truly decentralised network ?
