That's not really how we should attract people.
Instead of telling them 'hey, invest in BTC you will make money!' what about to tell them 'hey, see how BTC is useful'. It's better to see them coming as 'real users' and not as speculators.
That's how I think mass adoption should come from. (without denying that there will always be speculators)

It's a market with low performance (a subjective term) but it's a fairly reliable and safe market. Not like gold, but not far away. Something you don't have in the crypto market. There are still great opportunities in but more in commercial real estate (offices, warehouses, etc.). Of course, the yield is not the same but the risks are much lower.
