i think the greatest part of btc is that every altcoins could be exchanged based on btc in an exchange.
bitcoin was one that brought blockchain into our world(which was revolutionary), and everyone knows btc, while they might not know other cryptos(even including ethereum) if they have no interest.
The power of famousity made btc stable(not in price though), and we know that it's not gonna fall down. (unless blockchain was found to be something defective technically)
the weakest part?
i guess it has no priorities in technological matters than other altcoins.
i admit and know sure that what btc brought to us is a revolution and can say for sure that the concept it brought made possibilities to make sth a "money" other than gold, not "currency."
but i doubt that btc could really be a "money". not only to say the btc's price variability, everyone knows that btc has many technological shorts and there are a lot of others (eth, qtum, ...) that are way superior in terms of technological parts, starting from protocol agreement structure.
i think that there is a long way left to go when we can say sth a "money," but do you think it could be btc? what is your opinion?
