I can't believe people argue that BTC is not a bubble.

Has it exceeded its intrinsic value? - yes
What value: currency - only 1% used to buy stuff; store of value - limited numbers but its not like other commodities that have a use e.g. gold & jewelry.

Has it corrected? - yes, 25% last week

Is it still correcting? - probably

Is BTC blockchain tech being surpassed? - yes, blockchain 2.0 and now 3.0 emerging.
