...when your trading profits or hard earned tokens paid for your rent a couple of months a year, or why not every month...
When you buy yourself something nice once in a while like 
When you're able to make the end's meat through blogging like some fellow bloggers are doing in here, investing or trading second layer tokens, participating in airdops and collecting sats through faucets.
When you can send your love over seas with lower than imagined fees.
When you take your loved one to dinner with dividends paid from... I don't know what cryptos you'd been stacking for a few months, or years...
Mass adoption for crypto, at least the way I see it through my Eastern European non expert eye, is definitely not hodling and hodling for an entire life and end up dying of a heart attack with no one having access to your private keys. That's greed and it doesn't matter you stack gold or Bitcoin, is the shame shit.
Making billions out of crypto and not sharing at least a few leftovers with the less fortunate ones is definitely not mass adoption.
Mass adoption, is tokenizing the mundane and putting that crypto fishing rod in the hands of the hungry ones so they won't need to beg anymore or live in poverty.
It's recreating a centuries old crooked and outdated economy and spread wealth through this magical internet money that can reach anyone in this world having an internet connection.
Mass adoption first and foremost is creating streams of income into this new digital economy era where abundance incentivizes to spending and keeps these wheels spinning for and by everybody.
It's buying art with Bitcoins, donating sats to homeless, and eradicate poverty once and for all. Poverty shouldn't even exist on this planet if you ask me, with all the resources we have.
I doubt any other planet in our galaxy has the abundance potential we have and there's still so much poverty around us. Greed's the only thing that keeps some in poverty and others in excessive abundance.
Mass adoption is definitely not storing hundreds and thousands of bitcoins for decades and do nothing with them. I doubt Satoshi has ever envisioned bitcon and the cryptocurrency concept for that.
Wealth needs and has to be spread. That's how I see mass adoption, as some sort of abundance era where everyone lives with a purpose, is rewarded for his efforts, doing what makes him/her happy and fulfilled.
When some collect the most out of what is to be collected and refuse to share, robbers are born and beggars come to life. Mass adoption for crypto=wealth distribution and access to the new digital era.
It's about revolutionizing the industrial revolution, if that makes any sense...
Enough with my cheap excitement and philosophy though. How do you see crypto mass adoption by the way?
Thanks for attention,
