It would be nice if you acknowledged what effects this would have on Bitcoin.
this was one of your most sensible post and it seems you have come around to some my line of thinking. there are some things I take exception with though...
Somewhat, if value is created on a SC that is greater than that of Bitcoin the Bitcoin stays there.
It is not that the value is greater but merely different. Sidechains serve a different utility than BTC. Some might value convenience more (SC), others prefer security & liquidity (BTC).
Decentralized SC that function as a means of exchange and use merged mining will probably offer the most security miners will mine all viable ones and the difficulty will be in close equilibrium with Bitcoin. They can be thought off as secure as Bitcoin.
I'm glad you are able to come to that conclusion as well. Some it appears are to shortsighted to believe this could happen.
The users will go wherever it's most cost effective to exchange value, on the SC an increase in value is reflected in the price of Bitcoin, however that increase in value is attributed to being the biggest network with the lower fees, this increase in BTC value won't be reflected in mining revenue because it comes at the expense of sacrificing profits, leaving the network less secure.
I'm having some problem with that train of thought. First, it seems to me that the increase in value is not originated on the SC. Some will suggest that scBTC are traded on exchange but I don't find that to be convenient for users. Who would buy a premium scBTC on exchange when you can buy a regular BTC and convert it 1:1? Therefore, it is BTC's value that increases because of users finding value in the attached SCs.
Having said that, I'm not sure about the jump you're making about Bitcoin "sacrificing profits" and miners subsequently leaving the network less secure. Maybe you can expand on that?
The SC that offer additional utility at a premium or greatest arbitrage will alow miners to grow and secure the network, that hashing power is distributed over the whole network, those coins that earn the most for miners, when this type of growth happens will incentivized to mine those SC, they will drive new investment in mining and become more secure. In this case this network will be growing and Bitcoin and other SC will be getting the benefits of added security.
Agree with most of that
This growth is inflationary taking value out of Bitcoin, the market locks it in. I'd only consider the growth inflationary because that is value on top of Bitcoin in that scenario Bitcoin is dragged up but it's not the source of the growth.
As stated above, I disagree with that logic. Bitcoin is the source of the growth because Bitcoin is the underlying monetary unit. Users will buy BTC to participate in this economy and access the different SCs. Bitcoin is never "dragged up".
