It seems you have chosen the wrong word "financial freedom". There is no correlation with your exact explanation that might be the freedom and efficiency of transactions using cryptocurrency.
Financial freedom is a condition where a person reaches quite a lot of savings and is relatively safe, and the results meet his needs to live the desired lifestyle. Financial freedom can also be defined as a phase when we are in peace and the choice not to work anymore for money, because money is working for us (passive income). What is meant by passive income here is money that goes in without us having to work. while active income is income earned from working and then paid or earned wages and if it does not work will not get income.
The essence of financial freedom is that your passive income each month can meet your monthly expenses. For example, spending per month is USD 1000, then you are financially free if your passive income every month is USD 1000 or more.
Financial freedom can only be achieved through passive income, ie income earned outside of work that can support you, with enough passive income, you can be financially free for life even if you resign from your job.
