5 was me being somewhat sarcastic. I see so many people on bitcoin forums saying something like "Wow, the price has really gone up, it's going to the moon now, I just spent my retirement betting everything on bitcoin with 25x leverage on some shady chinese exchange.

Then a week later they're on suicide watch because the price went down 5-10% and they lost everything.

On some level, it's just common sense. A bitcoin is a bitcoin. If bitcoins didn't suddenly become more valuable for some obvious reason, then if the price has doubled in a few weeks, then that makes it a worse time to buy, not a better one.

I will never understand why people suddenly want to buy something after the price has gone up a bunch, because the price has gone up. You want to buy it before. Obviously if the price went up because the reward halved or, i dunno, citibank started taking bitcoin deposits, that's a different story, but just jumping in because of FOMO is stupid. (I saw the same thing with Nvidia, and warned people out of buying it and sold most of mine to lock in profits after the hype train started getting out of control in the past few weeks.)
