Yeah I’m not sure if you can call it “fresh”, but they sell fruit.

Four body problem?

Here’s the thing. Either it is all speculators and someone will be left holding the bag, or it’s a real investment.

Do you believe now that it’s a real investment? If so, then there’s no reason not to buy in now.

If you don’t believe it’s a real investment, and the price could crash at any point and you lose all your money, then it was as true back then as it is today and selling out was the wise thing to do even if in hindsight you could have made a lot more money.

Many people would compromise though, sell half to get their original money back and leave half. Then sell half again when/if it doubles, etc.

My understanding it’s the other end of a one way USB cable. Normally the cable is attached like your mouse or keyboard, or commonly these days USB C, but if you are plugging in USB and it’s not USB C but the cable unplugs at either end, one will be USB A and the other USB B so you can’t put it in backwards like you could if they both has USB A.

Early android smart phones used USB B micro or mini, but printers have no need to keep the plug small.
