In no way, shape or form would a crypto implosion be anywhere near the financial crisis in impact. It’s just not systemically important. It’s essentially “phantom wealth” not underpinned by any economic reality - even more unglued from reality than esoteric derivatives.
From 2007 to 2008, for example, global wealth declined about ~10% [1].
There's not much room left for central banks before we officially enter banana town. If cyrpto implodes, it could easily be worse than the financial crisis - which means, regulators have an interest in it NOT imploding.
