Do you ever feel that this is a hobby that you can't really talk to anyone about?

How do stablecoins make money besides buying treasuries with their peg hoard?

What happens when bond yields come down as they have already done in Europe?

In my country, gains from stocks are taxed 15% when selling, but gains from ETFs are tax free.
Dividends get 30% withholding tax from the US and an additional 5% tax here, but ETFs that are domiciled in Ireland and Accumulating only pay 15% withholding in the US and no dividend tax here (since the divvies are automatically reinvested).
