> This isn't the Bitcoin of 2015

I agree, because I used bitcoin in 2015 and it actually worked well instead of being crippled to a few transactions per second for the whole network.

How are they getting their balance on to the bitcoin chain? How much does that cost? Once they are in control of their money and actually have it on the real chain and not some wallet app maker's sub-chain they still have to eat more giant transaction fees.

This approach will only work for people using this app, which defeats the whole purpose.
