With the digital world all you need is the information and data plus smartphone and you are already mining , airdropping, trading crypto and fiat, hodling and investing in bitcoin. No one need to rely on saving of fiat in the bank and expect peanut from the bank instead of converting to bitcoin and hodl or invest for the bull run. These days many people would invest more than saving.
Mining is no longer profitable for solo miner, you ended up mining shitcoins.
Airdrop can be worth it if you're lucky enough.
While trading, not everyone can become a trader.
but if someone uses the money he receives and tries to start a startup, or some kind of anything, then eventually the one who spend it will be making more money.
Easier said than done, start a startup need to have high knowledge and the risk to fail is extremely high, it's easier to become a reseller or start a small business.
