We are in the early stages right now. People don't realize that for those who came when bitcoin was at 1k, people who bought at $100 were the early adopters. For those who first bought at 10k, people who bought at 1k were early adopters. The truth is, you are still early adopters simply because the market penetration is almost none and so is Internet penetration. If I'm not wrong it's at 60%, so almost half of the world has no Internet access, so they never had a chance to buy bitcoin.
The internet network is still very minimal below 2015, so only a few people can connect with the internet and get to know Bitcoin, and I think it is also the initial stage is the adoption of Bitcoin in the world.
However, on that day people buy at the initial stages never think that there is a Bitcoin guarantor in his value, and even today no one can guarantee that Bitcoin can be even more valuable.
Just like nobody can guarantee that you won't get cancer tomorrow, or that you won't get hit by a car next time you walk around town, or that you won't choke on your food and die...
Nothing is certain but death (and maybe taxes, but I haven't paid my taxes a few times and I'm doing fine), so don't make it sound like no guarantees is something that is slowing down bitcoin adoption, or making people scared of it. There are also no guarantees that they will keep their jobs, or that their currency will not hyperinflate.
