Here is how I see the timeline:
2020: This decade will be the consolidation of crypto, and bitcoin will be on the lead because no altcoin will be able to clearly defeat it for what it has to offer. Every competing altcoin will continue to be seen as a gimmick/ripoff with no support
2025: Lightning Network is now fully operative and competing against all fiat payment system.
2027: The price is now 6 figures, the release of new coins is very low.
2030: Onchain transactions are now expensive, only used for 100+ USD dollars or more. Onchain BTC is digital gold. Thanks to the conservative blocksize, corporations can't control the network. Everyday non important transactions are processed on the LN. Trillions of transactions per second are happening. Banks are struggling to justify their existance.
2030+: BTC is the world currency, banks fully support it and act as a way for newbies that cannot take care of their own bitcoins, they do it for them. People that want to be sovereign still control their BTC.
1 BTC is worth 1+ million a coin. Chinese mining no longer leader. Intel and AMD and nVidia now competing to be the top miners.
