Elon says he is selling Tesla stock to pay taxes, but he has sold far more than is necessary to pay off his taxes. The fact that the founder/CEO (who presumably has unparalleled access to insider information) is doing so should be a huge warning to anyone not blinded by the Tesla hype.

Only reason it's still alive is that Grab has been burning billions of dollars for years without any lasting benefit. Undifferentiated products in sectors with no barriers to entry. Doomed to fail once SoftBank finally decides to pull the plug.

Very pessimistic on Grab. They are facing massive competition in every sector they are in, and compared to their competitors their offerings are either undifferentiated (ride hailing, food delivery) or downright inferior (finance).Every new sector they expand to just brings even more competitors for them. What's worst is all of these competitors are largely focused on a single sector (e.g. ride hailing - gojek, food delivery - food panda/deliveroo, finance - banks), and can devote all of their resources to defending their market share while Grab's resources are spread out.Some people see this involvement in multiple sectors as a good thing due to network effects, I see it as a sign of desperation as they are not able to be profitable in any sector. As a Grab user myself, I can safely

I can't decide whether the Tesla fanboys are delusional or naive - do they really think the musk would sell his own shares if he didn't think they were overvalued?

It's a bubble. Isn't the first, definitely wouldn't be the last. Still, retail (and indeed, institutional) investors are not always rational and it may be a long time before it finally bursts. You don't want to be left holding the bag when that happens. "Invest" if you like, but don't put everything in it. And definitely don't trade on margins with this counter.

I don't think bitcoin is anything like gold. Gold is valuable as it taps into every human's innate desire to show off their wealth. 3 traits allow it to do so - it is eyecatching (sparkly and shiny), easy to wear (jewelry) and credible (if you wear it, you show ownership over it). Bitcoin has none of these traits - it only exists virtually (so you can't attract attention or show it off) and isn't credible (anyone can claim to own it, impossible to verify).
