The block size increase is not going to happen - Segwit2x was it's last chance and no-one is going to bother with another campaign.
Scaling is going to happen via alts. [...]
Basically scaling is happening very fast - by by-passing bitcoin and using alts.
it is something that I've never understood very well. It would seem that to convert bitcoin to altcoin you first need to have your bitcoin in an exchange. And provided you don't keep your founds
online (which is not secure to say the least) you need at least one bitcoin transaction to do it. So I don't understand benefits of transacting through alts, really, if sending bitcoin directly is one transaction too
Unless you ment abondoning bitcoin completely and using alts only (?)
Once bitcoin started hitting scaling problems in mid 2017, loads of exchanges enabled the ability to buy alts with fiat.
For example on Kraken, you can buy Bitcoin Cash in USD or EUR, Ethereum in USD, EUR, CAD, JPY, and GBP, Ethereum Classic in USD and EUR, Litecoin in EUR, and USD, Zcach in EUR, USD and JPY and so on.
On the Korean exchanges, pretty much most alts listed can be traded directly for Korean won.
You can now by-pass bitcoin entirely. All that is left is merchant adoption of alts, and this is accelerating - lots of merchants have enabled ethereum, litecoin and bitcoincash. And Overstock allows people to use Shapeshift to purchase goods with about 12 alts.
Scaling is happening in the alt space.
