No coin can have as stable of a value proposition or the empirical evidence of security as bitcoin. The coin's you are quoting are not intended to have these qualities. Ethereum hasn't even decided its inflation schedule as I understand and litecoin has a $200 million cap right now. You are calling me religious for making well reasoned claims but you are simultaneously speaking to future scenario that doesn't exist today.
Bitcoin offers these things that no other proposal can, and an increased transaction capacity and low fees is not a valuable solution as evidenced by the market cap of the many coins that offer it.
Bitcoin isn't valued because its cheap and fast, its valued bitcoin its value proposition is secure in other words its a digital gold/inflation hedge.
You stated BTC would be the Best Forever,
Can you really take yourself seriously after that.
Things I use to hear IBM makes the Best Personal Computer, no one will ever complete,
Until a Little Company called Compaq came along and guess what they made better computers and even they fell in time to HP.
Things change Hard drive tech started with rll, then mfm, then scsi, then IDE, and now SATA and others.
BTC is the rll, it won't last without some serious upgrades.
If a product can hold the market for 10 years , it did really well, expecting it to last forever is religion and you will be disappointed.
Or are you still using that 8 Track tape in your 1970s car.
