The market for Bitcoin is already saturated, everyone in the world have heard about it and those who wanted invested in it.
Due to this I wouldn't expect fast grows from now on and for that reason 1 BTC will never be enough to be wealthy, maybe if you live in third-world country...
Even if bitcoin price reaches $100,000, owning 1BTC and thinking we can live a rich life with everything is just an illusion. If we want to have the life of a rich person, in addition to earning a lot of money, we need to maintain or increase our assets, then that will ensure we have the life of a truly rich person. To do that, we need to put in more effort and work, not just rely on bitcoin.
But I don't think the bitcoin or crypto market is saturated, I even believe this is just the beginning and the demand for bitcoin is still very small. Look at the capitalization of bitcoin and the entire crypto industry, it is even smaller than the capitalization of a US tech company. Or Bitcoin's market capitalization is equal to US defense spending in just 1 year. So how can it be said to be saturated?
Gold market with 16 trillion market cap, US stocks with 50 trillion market cap and bitcoin only 1 trillion. Which market do you think is saturated?
