While the newer people will look into other opportunities beyond Bitcoin the risks I think are higher because unless you select very carefully you. might end up losing money more. This is because unless there's a clear bull market (this yet to be confirmed by current market) not all alts will show an increase in their token prices, mainly because of the lack of utility and value they provide.

Sometimes people forget that you don't have to own 1 whole BTC to still make a profit from the BTC price surge (which is definite to occur at least in the long-term) and instead opt for different alts like meme coins etc.

Fundamentally, if you spend enough time researching the best projects you can still make a decent profit, and yes, BTC investment is probably the most passive earning.
