Casual retail investors can't get over the fact one BTC is so much money and doesn't return anything. When they see other coins are cheap and give 10% or 20% in "interest", and can rise in price like crazy.
Of course it always ends in tears...
Guys raise and argue those same points in this thread in terms of wanting to get yield on their bitcoin.. blah blah blah. when they seem to not appreciate that bitcoin is already designed to pump forever, in the sense that bitcoin already has a built in pumpening which is its soundness.
Yes the very limited money printing (mining).
From what I read Luna had limits on what could be printed in a time period, but when things started going wrong they immediately changed the limits, and some hours later they were printing billions of coins a minute, then dozens of billions, it was totally absurd.
