Bitcoin is a new revolution of monetary system that might be our future that's why a lot of people are preparing already through investments and holding. Although most of the investors purpose is for profit, some are looking at it as a security for the future so that if ever bitcoin becomes legal in the future and became an official currency, they will have all the advantage towards those who didn't invest on bitcoin. Who knows what the future holds so it would be better to find a way on how you can make sure you can suffice all your family's needs when the time comes.
Bitcoin is not only an important invention in human history, but also a kind of civilization. It has gathered a powerful consensus in the world and solved many problems. For example, users of Bitcoin have complete control over their transactions; Merchants cannot impose unjustified or unobtrusive fees that might occur in other payment methods. Paying with bitcoin eliminates the need for personal information to be tied to the transaction, which provides significant protection against identity theft. Users of Bitcoin can also protect their funds through backup and encryption, which is much more secure than fiat currency, so I believe that in the future Bitcoin will become a means of payment for people, not just a means for investment.
