Bitcoin is the future. Future what? The word future is rather vague.
Indeed OP's statement is too vague. The moment OP left the statement open, it become subject to different interpretation.
Investment is also future-focused. You do not invest for the past days or the present; you invest for the future.
And maybe I stick to this. If OP means that Bitcoin is the future, possibly he is thinking that bitcoin will go up in a price that can elevate any one's status of living and can secure our next generations financial aspect.
It maybe hard but yes patience is needed to achieve that and of course a strong hand to hodl.
I derived on that idea because of this earlier sentence of OP
From my last post about Bitcoin investment, following the valuable contributions of members of the forum, I learnt that Bitcoin investment is not just something that blossoms in a few days, rather it takes patience.
But I guess you are referring to Bitcoin's potential of becoming the future currency. I am also positive that it will eventually happen although I think it will take a good deal of time and further developments to its protocol. There are several reasons why I think so. One is the fluctuating price of Bitcoin. You cannot use a daily currency with such an unstable price. Another would be the scalability of Bitcoin. If the billions of people on earth will use it, it simply cannot keep up in terms of catering all transactions. There will be severe clogging in the network.
Bitcoin is developing, we are talking about the future not the current situation. I believe by that time, lightning network or maybe a better system will be implemented on Bitcoin blockchain to cater all these needed volume of transaction. In due time, Bitcoin will scale.
In general, Bitcoin is the future, this will be the currency of the world.
I am pro Bitcoin but honestly I doubt that Bitcoin will be the currency of the world, probably an alternative, yes.
