In simple language, everyone already knows about crypto in general and bitcoin specifically.
that is wrong.
If they wanted to invest in crypto, they already did so. If they didn't, they wouldn't, as simple as it gets.
that is even more wrong.
why? it is simple, a lot of people have not even heard of bitcoin. they may have seen the name, saw some article online, on TV,... but they never even paid attention to it. it was something they passed by. and there are a lot more people who know about it, read the articles,... but they didn't invest in it because they were afraid of its future. for instance instead of reading what bitcoin is they read what Warren Buffet said about bitcoin so they decided not to get involved with bitcoin.
this will change in the future. the same people will start learning more about bitcoin and know how bullshit 99% of the articles about bitcoin that they read were. and the rest who haven't heard about bitcoin will know about it and that way the adoption increases.
So what does it mean for us all? Essentially, that there is little hope for bitcoin to make new all-time highs any time soon or even just local highs beyond minor rebounds.
even if we assume that no new person is going to adopt bitcoin (which is simply not true) the same investors are still investing more money in it so in a way price will rise even there were no new adoption!
Over the long term, we will be moving closer to the use value of bitcoin and other coins (if there's any in them in the first place), with the price closer to what it would be if there were no speculation at all.
there are no other coins. there are shitcoins and then there is bitcoin. the value of these shitcoins are never going to be even remotely close to bitcoin's because they are shitcoins!!! and you can never remove speculation, it will always exist as it exists in any other object out there from currencies (fiat) to goods.
