If bitcoin's price continues to rise, people will soon be unable to ignore it; it will be perceived as the 'gold standard' for currency.
your problem like many others is thinking that bitcoin is one thing: price
when the fact is that whether people ignore bitcoin or not has nothing to do with its price. price rises and falls only attracts one type of people and that is day traders who are interested in fiat not bitcoin and want to use bitcoin to earn fiat.
the funny thing is that the price drops attracts these people nearly the same as price rise does! because day traders make their profit either way.
This is true but it doesn't only attract day traders, there are many people that treat Bitcoin as a long term investment and the issue is that these types of people only seems to buy when the price is going up. And they generally sell when there is massive selling pressure and leads to huge price declines kind of what we saw in Nov 2018.
People assumed that $6000 would break and the lowest will be $5500 but in reality look how low it ended up going. So basically any long term investor that bought above +$10000 ended up with huge losses when they sold at around $3000.
This is why Bitcoin has very fast pumps and the dumps are usually more slow bleeding but eventually there is a capitaluaton event and it reverses.
