Without very rapid advancement of computer hardware, achieving decentralization, mass adaption and low fees at same time is near impossible task.


I think OP is talking about Layer 2 being less decentralized, see https://www.bitcoinlayers.org/.

Just with Lightning, you would still be able to do that. You lock your Bitcoins in scripts which become Lightning channels, so they are stored there safely with Bitcoin's L1 guarantees.

If the channel is unidirectional and you are at the end of a Lightning "spoke", i.e. if you only use it to pay and not to receive money, then there is also no risk for the channel state to get "rewinded" to an earlier state. This means that in this case, there is no security tradeoff. Basically, you only "bundle your own transactions". If you open a LN channel with $10000 in it and pay $100 fees, Bitcoin is still competitive.

But even if you do participate actively in the Lightning routing (opining several channels in both directions), the security guarantees are still those of the Bitcoin consensus and you only have to monitor the state regularly to be able to initiate a channel close. There is no "middleman" like in the currently existing Ethereum rollups for example.

The logic is quite simple as adoption increases so also will price follow and that simply means that smaller unit of SATs will have bigger values and this would also mean that smaller amount of SATs will be paid as fees or transaction fees rather to miners. Layer 2 upgrade will not be a problem in fact it was a fork fix to improve efficiency of transaction by saving block space and as a result reducing congestion.

The only reason I see or fees becoming bigger is if congestion later becomes an issue and I really don't see that happening anytime soon besides there is always room for an upgrade. Little random congestions is quite normal sometimes but a general long session of congestion like something similar to what happened around 2017 and 2018 will be a little difficult.

Everybody has their views.
Just like I believe Bitcoin price is undervalued
Bitcoin didn't necessarily deviate from its intended purpose
It's more like it evolved and added as a store of value
And yes though Development has been slow and cautious it's price payed for security.
Scalabilty is been solved by Layer 2 network and in the future we can see something better than LN.


All cryptocurrencies are speculative in nature and it wouldn't be easy for any to take over Bitcoin as the pioneer of the cryptocurrency.


It's true that many are buying Bitcoin as a speculative asset but many isn't all
And as time goes on they would understand the flaw of the Fiat system.


Either scalabilty remained stagnant with no improvement which is very unlikely or $100 of then Would be a dollar of now.

I verily understood what you mean. So indirectly lower class holders who're quick to sell at any moment accountable profits no matter how small it may be would be optional to keep holding their asset for a longer time other than planned just so they can increase the value of their holding logistically on transaction fees and how to make profits without lost.
And ignorant to follow according may be at lost otherwise the average and lower classes will be forced to hold longer to increase their incomes before placing a transaction or trades.
Really going to be inconvenient if the fees gets to keep increasing up to unaffordable value for the lower classes.

Bitcoin transaction fee is not too cheap, it's expensive especially if you make a transaction with low value. However, it is cheap if your transaction value is not too small, and if it is big value, that's good choice. Because Bitcoin transactions are irreversible, not like bank transfers or many other methods.

Compares to other years in Bitcoin history, it's time with cheap on-chain transaction fee.

Now you can move your bitcoin with fee rate at 3 sat/vbyte, with a confirmation in a next one block.

If you use non custodial wallets, with control of UTXOs, you can control your inputs, outputs, fee rates, and I am quite sure that you can avoid $100 transaction fee.

Bitcoin other layer technologies.

Because people would still see it as the thing they see today - a store of value and an investment mechanism.
 

One very important concept with BTC is freedom, now do you want to dictate to people how they should use a 'free' currency. I have never had a problem with how people use BTC, it is their keys, so it is their coins, and not yours or mine. I believe that instead of us complaining about how other people use their coins, we should use ours in the way we think is right and support the network how we can.

Bitcoin is a settlement layer which big corps will use. (Like banks and tech giants, or/and even countries) Common folks like us will use alts. (Litecoin, dogecoin etc)

Remember:

Btc = gold (money of gods and kings)
Ltc = silver (money of plebs)
The others = copper (wire material)

Meaning, if you can’t afford to pay them fees, use something else. Only the very elite can use btc and it seems you are not one.
