I don't particularly believe there's much or any skill involved in trading crypto, whereas there is a tad with shares as they're somewhat calmer and more measured.
Crypto is so relentless, shameless and chaotic that I'd assume anyone applying principles learnt elsewhere will get their arse handed to them rapidly.
There are definitely skills involved in trading crypto, but they are crypto specific skills. You learn them only from years of trading crypto. You can't just use your experience from trading stocks. An example is always buying at a certain volume and percentage drop, and learning how walls lure buyers and sellers.
