the reality people need to realise is

FIAT spenders use debit cards 40 times a month on average, but because bitcoin is not acceptable in every retailer

the average spender only uses bitcoin once a week/once a year.(5 a month) based on person-merchant

the only real niche LN has is the faucet raiders and exchange day traders that will want to arbitrage daily. (average 10 a day)

knowing people cannot predict spending habits beyond a couple weeks and wont risk locking entire hoards into year/eternity long channels. the reality is channels will only get funded with pocket money amounts and for only a couple weeks lock periods.

these things limit the available funding for route hopping to occur

LN is not.. and i emphasise this.. is not about the funds of [A-B] $120 actually moving out of the channel. LN is about having 'pockets' of funds that 2 parties share. and they have a couple pockets dedicated to share

think of it like a 3 legged race where the legs are tied together with a fanny/bumbag. where the money stays in the fanny/bumbag. but who owes what % of whats inside the fanny/bumbag is agreed by the 2 people tied to it.

so get 5 people and play a game

EG

[A-B] [B-C] [C-D] [D-E] imagine BCD only trust $60 for 2 weeks

A need to deposit $60 (1 channel with B of $60)

B need to deposit $120 (2 channels of $60 with A and C)

C need to deposit $120 (2 channels of $60 with B and D)

D need to deposit $120 (2 channels of $60 with C and E)

E need to deposit $60 (1 channel with D of $60)

[$60-$60][$60-$60][$60-$60][$60-$60] now imagine if A wants to pay E $60

[$0-$120][$60-$60][$60-$60][$60-$60] then

[$0-$120][$0-$120][$60-$60][$60-$60] then

[$0-$120][$0-$120][$0-$120][$60-$60] then

[$0-$120][$0-$120][$0-$120][$0-$120] now finally after 4 hops E has $60 extra thanks to the 'routing'/hops

technically B, C, D still has $120 but its not spread over the channels

for instance B has $120

but has $120 in

[A-B] but $0 in

[B-C] channel

meaning if B wants to pay D.. B can no longer user the

[B-C][C-D] route because B doesnt have funds to pay C to pay D.

instead B needs to go backwards through

[A-B] because thats where B's funds are, so...

B needs to give A.. then A needs to find a completely new route or create a new channel that is funded and has a new route to E to get E to pay D. or B needs to set up a new channel to fun that has a new route to E.

.. it may seem complicated but its alot easier visually if you just get 5 friends and 3 fanny/bumbags and put $120 of monopoly money in each bag ($60) each person... and without physically taking the paper money out.. agreeing who owes what inside each bumbag and then finding the best chain of hops to fund the group..

and see how long the 'payments' last by making up scenarios of buying each other things.. you soon learn the limitations of LN

next time you are at a bitcoin meet-up.. try it with the other attendee's. as its a very helpful visual display
