The best thing about bitcoin I can see, is that i can transfer it literally everywhere I want, and you can also withdraw it world-wide.
Yeah and if your friends and family members are using bitcoins too then it will be much easy to transfer bitcoins to their wallet with minimum fees and even selling bitcoins and transferring money to bank account is much easier process as you will receive money instantly into your bank account.
That is a really optimistic prediction, I wonder on which year you date such a scenario?
Because I would not expect such a situation before 2025, you need to remember that before bitcoin or any other cryptocurrency will get accepted by normal citizens of different countries, many years will have to pass.
Also, we are still having the big issue- the blockchain network sometimes suffer under the big traffic, and there are problems with correct maintaining with so many people using BTC.
But I have to agree that the perspective in which my family would have sent me bitcoin is a really nice thing. But im afraid this is still a dream, unless you have very smart family
