And yet some persons are still optimistic asking if it's actually the right time for them to get involved in Bitcoin thinking that maybe it has grown too much and has become too late for them
By asking like that, they are pessimistic, not optimistic. They are pessimists about Bitcoin future now with such questions but by asking, they are ready to learn and change to become Bitcoin optimists.
well anytime I see such conversation or discussions what I do is smile because as a Bitcoin enthusiast we don't see it current price as big but something that's way off from its starting point because I believe is still very young and getting involved is definitely never too late that's if you are not in doubt of the process.
Bitcoin provides us many things: chance to invest, chance to use its as a mean of SoV (Store of Value), mean of peer to peer transactions, mean of owning our own bank. On top of that, freedom, no dependence on central or commercial bank on security of our asset, is key.
Price is attractive for investors and one of reasons they spend money in Bitcoin investment but value and price won't exist if lack of other more fundamental things.
