My most important question: Which is better, staking or investing?
Staking doesn't produce anything of value, it's just useless inflation. For every "free" coin you get by staking your portfolio is depreciating by a similar amount (or more, if some other bagholders have masternodes or some other contraption that produces more inflation).
I remember my early days in crypto. I was so excited to stake my crypto for the first time.
I stake Digicube (CUBE) on that time. I am so happy to get free crypto by doing nothing.
Until.. a few days later the price drop hard every time the stake period ends.
Yeah, I am that dumb. But I learn something from that moment.
Staking is a competition to push down each other (staking participant) in asset value.
