Is Bitcoin stupid?

What is it good for? Why do I need bitcoin? For transactions? For a hedge? when it’s so volatile?

Why would people take their money out of a bank, then put it into Bitcoin? Where it could lose 70-80% of is value at any second ?

Why does the common man, or anybody, need a Bitcoin? —. I can’t think of any reason.

They say it’s like gold. well , why not just buy Gold?

I get that blockchain will change everything. but why do I need a BTC?

All that is needed for a digital age , is a digital stable coin. that’s it.
