Currently of the biggest advantages of bitcoin is (as some people would consider it) being (centralized mining aside) it's lack of central authority
but, that being said, without a central authority, nobody is actually "in charge" of promoting it
Hence, we see no active marketing (in a sense that we would be seeing if
BTC was owned by BoA, Citigroup, Alphabet, Paypal etc..
we see what we would call exclusively P2P transfer of news at first, and in later stages no words short of phenomenon describe it.
so now, i think this is the biggest advantage of bitcoin in it's healthy growth!
because you see, people did not see the bitcoin like some small new thing that was worth 0.43$ (shot in the dark here from the first year of bitcoin value)
they heard when it was at 1100$ (first time
)
or they heard after it happened, and thought "wow, i'll be damned"
next, that tiny little geek laughing stuff stayed on course, holding firmly above a price no stock would be ashamed of
next thing, what do you know, 1100$ again..
and wait, holding firmly?
we have the ear of the world investors now, watch those volume charts and prepare, money will start pouring in, and since we are limited to 21 000 000 bitcoin, if there is 100 000 000 000$ inside bitcoin (a microscopic drop in yearly flow of fiat currency trading) price has no way to go but up
so what i think, the biggest disadvantage became the bread and butter that reaped success
have a good evening
