If someone wants to give me money and happens to have it in BTC, either they’re going to convert it or I am. I might as well make it easy for them. (I’m generally anti-BTC, but if I were taking donations, I’ll find a way to take what you want to give me.)
Every time someone says "if you don't like it here, go somewhere else / home" with an anti-immigration stance (even if they're talking to people born / naturalized in that country) they're asking them to be an immigrant elsewhere.
Of course it is, since a block holds a max number of transactions. Say a block can hold between 1 and 1000 transactions. Then, mining a block takes 1 kWh. This means that a transaction takes between 1 kWh and 1Wh, depending on transaction size (number of wallets involved, other metadata etc).
