You're completely missing my point. Insider trading is a complete no-no and when it comes to dealing in shares there is total transparency to expose such insider trading
I think you are misconstruing the concept of insider trading.
In general parlance 'insider trading' is considered a no-no, because of the
potential unfair advantage to those who hold valuable information, And the
actual unfair advantage in cases of proven corruption.
But not all insider trading is illegal.
A company CEO who increases her shareholding in the company she operates, on (perceived) favourable commercial news, is perfectly entitled to do so as long as it is not hidden away from the public (assuming the purchase of stock by itself has made little material difference to the stock price ).
Is it insider trader (by corrupt practice) if the market perceives the CEO purchase of shares as favourable, in turn stock market speculators drive the price up?
A bank clerk processing increasing amounts of mortgage approvals may reasonably deduce that property prices may start to increase in the near future and act accordingly by buying his own buy-to-let apartment before the public is made aware of the increase of mortgage applications.
In both instances, this is insider trading, but it is not illegal.
For it to be illegal, there has to some proven intent to profit by corrupt means - deception, misleading information, non-compliance with regulatory requirements etc
There can be no question that most people in Tesla's accounting department and their friends an relatives filled there boots with this totally to be expected btc spike - they will never be found out.
I'm not sure if you are suggesting they filled their boots with Tesla stock or BTC, or both? I assume you mean BTC because of the "they will never be found out" reference?
I'm not convinced it is illegal at all, but as I referenced, if it is shown that Telsa have offloaded their BTC holding in advance of a reversal of their BTC trading position, then I think that would raise a red flag.
