As for %s there is a combination of factors and they are all related when it comes to learning: A- Touch points: you might hear about Bitcoin the 1st time (ignore it) then another (a bit of research but your friends tell you its a scam), then another (ignorant still but skeptical and then you may take a deep dive but it depends on B)

B- Price: price is always a signal for almost everything, humans give a lot more attention to things when they appreciate in value (most BTC adoptions happen in bull markets)

As for Wallets, its Wallet of Satoshi as it has the best UX (yea its custodial but new comers dont know the difference and dont care at all) but during their rabbit hole journey they will come to know the difference (in a nutshell I dont bombard new comers with much info as too much info = no info)

In my country Crypto is banned (no bank would touch it) so all the buying/selling happens P2P (physical face to face /via exchanges P2P both buy/sell USDT). I never convert any BTC to fiat and all of my LN balance is for zapping sats to quality content and to orange-pill participants of my workshops

Note: I've learnt not to push BTC to anyone, if they are curios I would answer questions objectively. To generate curiosity in anyone you can ask stimulating questions for them to think of and to also know humans are mainly driven by FEAR & GREED
