I'm not referring to the price of Bitcoin (we all know it's going to be $250,000/coin by 2022),
this is not the "price goal", it was one of the many speculation of what the price may be by then.
but the goal that it would be a legitimate alternative to inflationary government fiat currencies.
if by "legitimate" you mean something that the government approves then you are wrong this is not the bitcoin goal either.
Where Bitcoin goes, so does the rest of the cryptocurrencies. There's even somewhat of a dismissive attitude toward other crytpos in some investment circles;
there is a simple explanation for it, people don't care about altcoins!
I think that bitcoin continues to strive in the market. If you mean goal to reaching the approval of the government and become mainstream i think it has not reach to that point yet but the direction is and that it will be adapted world wide. There is so much potential in bitcoin and with other altcoins emmerging it just means that people are at constant look out for a better crypto. Yet so far bitcoin continues to dominated the cryptocurrency world. Judging from the backlash against fiat money and negstive advertising financed buy group of people who are against bitcoin I can finally say that the goal yet to be achieved. One day I hope that i will become mainstream and once it does then by that time it had finally reached it's goal.
