What are the cons to criticism of BTC?

BTC has no real financial performance like stocks or commodities. It started to be a digital currency, but it failed to be because of its limited-capability transaction system and high transaction fees. The price only rose because of hype and speculation, but there was no real value behind it, so it's just a long-lasting bubble.

I'm not a BTC hater; it's just criticism coming from others who have some sense of finance but chose to stay away from crypto.

What are the cons of this criticism?
