To get rich from bitcoin it's too late because we won't get an exponential increase like in previous cycles that could be thousands of percent in a few years, if we look at the ATL (all time Low) in the current cycle it counts 3-4 times if we buy bitcoin from its lowest price in this cycle, then if you want to get 10 times to 15 times it might take 1 cycle to three cycles, but that's with the current count, it could be that bitcoin adoption occurs massively, such as the world recognizing bitcoin as a transaction tool or value as a foreign exchange storage asset throughout the country then 20x or more can happen again.
I don't think it's too late to get rich from Bitcoin. We can't predict the future; we might experience a high increase in the price in the future. If more big companies accept it as payment and more nations adopt it as legal tender or reserve currency, we might experience an excessive. It also depends on how much investors are willing to put in and how long they are willing to wait.
Bitcoin will probably grow more popular if we talk about decentralization, immutability, financial independence, transparency, and other features of Bitcoin than if we talk about its potential ROI. The former will attract solid supporters, the latter opportunists.
Only a few people are concerned about privacy and freedom. Most of them only have an interest in making money from investing in Bitcoin. And it is becoming difficult to enjoy privacy in this world because the government is gradually making it harder to carry out any transaction without KYC. A survey of why people are engaged in the Bitcoin space will show that majority came for profit.
