I think that right now it is not worth investing in bitcoin alone. This year, due to a sharp fall, he lost a lot in his popularity, which is still held by his former fame, and also due to the relatively high capitalization, which, by the way, is steadily declining. Although there is still a price dominance of bitcoin over other types of crypto currency, this may prove to be temporary, while the popularity of bitcoin is rapidly passing. So now we need to invest more in promising altcoyins.
