"Never"... that word should NEVER be used.
Byteball is a RADICALLY different algorithm that solves the problem of scalability at the base.
Sure, it needs extensive testing, but it deserves to be tested.
Bitcoin on the other hand has reached AGAIN a complete congestion time, and its network is probably under spam attack.
This exposes an intolerable weakness.
And if you know how the LN works, you understand that it won't be the final solution either.
In case you don't know how the LN works, here's an interesting article: https://medium.com/@homakov/why-lightning-and-raiden-networks-will-not-work-d1880e4bc294
And no I am not "pushing" for Byteball, I have invested on around 30 altcoins, and IOTA uses a similar Network Algorithm.
I am not here to make advertising, just saying mine after showing that there's something wrong going on in Bitcoin, and believe me, I'm really sorry for this, but it seems it took too long to Bitcoin to change and update its protocol, and it's making the end of Netscape: didn't keep up with competition and evolution of the technology.
Oh, and the price is tanking and my 4 BTC are stuck in shit and I can't exchange them.
