Now 2023
10 years later 2033
Now bitcoin price $28000(approx)
10 BTC = $280000
It is impossible to accurately predict what Bitcoin will actually do, but many experts believe that after 2030, Bitcoin will have a market cap of $500,000.
If it would possible then 10 BTC for retirement is highly enough.
10 btc will not be enough for retirement if the market price of bitcoin falls after 2030. But based on the competitive Bitcoin demand it is true that the market value of Bitcoin will increase a lot in the future.
In fact, you need to build on how much money you need in order to achieve financial independence. Bitcoin can be one of the components in your investment portfolio to diversify your investments and feel more confident. And then everything is very individual, for someone a few hundred thousand dollars will be enough for a comfortable life, someone needs a million for this. A lot can change in ten years, but I think everyone will feel more confident if they have a few bitcoins in their wallet.
