a future gripe we will have to contend with as (early-adopter) #bitcoiners is this:
“self-sovereignty for me,
not for thee”
even $100 weekly/monthly DCAs will become prohibitive
consider this a warning
Discussion
Fact check: true
Context: because bitcoin supply is finite, block space must be costly. New software for creating transactions and possibly new transaction types (soft fork) must be invented to more efficiently use block space to share the cost of block space over a larger number of users. This type of optimization is independent of layer 2 and 3 solutions. Example: signature aggregation. More efficient for dozens or hundreds of users to add an input and an output to a single large transaction than to have each transact on their own; with schnorr signatures now in bitcoin, you can represent all of the signatures as a sum…in effect, dozens or hundreds of signatures can be represented as a single signature. There are even methods of aggregation the span across blocks, but creating these cross block aggregated signatures is much trickier.
Here’s a 2018 blog post by wiulle on the topic. https://blog.blockstream.com/en-musig-key-aggregation-schnorr-signatures/
There’s a video of gmax discussing this well before this, but I can’t find it.
