I have not read the whole thread. Too much one-liner spam.
But OP's first point is not totally wrong. Most people don't realize that Bitcoin is a pretty expensive payment system. It depends, for now, from speculation - most people only buy BTC because they think they will get a higher fiat value in the future.
If you look at this chart you see why BTC is so expensive:
https://blockchain.info/charts/cost-per-transactionAs Bitcoin actually is inflationary (about 10%/year until the next halving), the actual "stable" value per token means that there is still a steady influx of value in the form of fiat currencies into the system. If the "fiat value" (=market cap) of the whole BTC network would be flat, that would mean a sinking price per token.
Now what has to do this with transaction costs? Well, the funds that go to miners actually are the reason for the bitcoin inflation. These funds (50 BTC/block, 3600 BTC/day and still 1800/day after mid-2016) are the
real maintainance costs of the Bitcoin network. They have to be divided by transaction volume to get the real transaction costs.
These costs are unlikely to go down significantly in the future, because miners have high energy consumption and hardware costs. So as long as BTC stays with Proof of work, it will be a expensive payment system.
That does not mean Bitcoin is doomed. It may be possible that with Lightning Network and other technologies BTC will evolve into a kind of "clearing" system where only a few high-value transactions will be recorded in the blockchain. We'll see.
But I would not ignore possible improvements like Proof of Stake and similar technologies (like
Proof of Burn,
Proof of Importance ...) because they have significantly lower transaction costs.
PS: No, Rimbit is NOT the solution. It's a pretty dubious looking altcoin.
