I think lots of noobs are interested in bounties & alts because they are probably too poor to buy 1 bitcoin & would rather own millions of shitcoins like SHIB or something.
I don't think this is the reason. Maybe in some cases, but I don't think most people is that idiot to not understand that more coins doesn't mean better. IMO, newbies (and not so newbies) look for a coin that can go suddenly x100 or x1000, which is hard, but still possible, for a shitcoin. For Bitcoin, at this stage and magnitude, I don't think it is even possible anymore, so it doesn't fit in the
get rich fast scheme many are looking for.
Please, don't misunderstand my words: BTC is still the king, and I hope that it will keep the crown in the coming centuries, but I don't think that anyone expects to get rich overnight by hodling just a few sats.
