@bbc.reporter ethereum will scale. There are several scaling developments, raiden in ~1month, also pos with casper, state channels, sharding, truebit. Keep in mind that no other project or development team currently can challenge ethereum foundation in development.
Bitcoin's blockstream/core has what, 100 devs or more ? And they keep chasing their own tails for many years now and all they could come with was segwit and maybe LN in 1-3 years. Raiden, LN equivalant, is weeks away. And comparing bitcoin to ethereum is like comparing a bike to a nextgen tesla.

Akasha will use IPFS and ethereum, because swarm is not ready.
