These are all problems invented by Crypto bulls to build a narrative for why Crypto is widely useful.
There are a handful of small, very poor countries where Crypto might have been better than holding local currency. But you also had to be poor in those poor countries for it to make sense for you to buy Crypto instead of hard assets like land or housing - if you were merely interested in bypassing monetary devaluation - and not interested in EXTEMELY risky speculation to get absurd returns.
The total money for people this might even have made a little bit of sense for is maybe $1Bn. Considering Crypto had close to a $3T market cap at some point - this is not a talking point. It's noise.
The real story - and the only story - is that Crypto is and always has been speculation.
