Unless we all want to lie to ourselves, in most places now, cryptocurrency is not being used daily for life stuffs and all we are just so keen about is the profitability in the long run.
Actually, people in Venezuela already started using cryptos to transfer money.
Their currency is losing value much faster than BTC can drop. It is being adopted there currently.
People are using bitcoin, dash or nano to buy food/clothes/water or to charge their phone. They have completely lost the faith into their national currency and started USING crypto.
While it is true that all cryptocurrencies seem to be just a speculative object in most countries, this does not apply to all countries.
And i am sure there will be more countries whose financial system will collapse. People in these countries might start adopting towards crypto too.
