We all take Bitcoin to be a digital asset
Well if you think all the fiat currencies in the world that are being traded on Forex market are digital assets then you can also call bitcoin that is also a currency, a digital asset!
But don't say "we all".
The price speculation found in Bitcoin so far makes it to have some features of the Nasdaq 100,
How so?!!!
I don't see any similarities whatsoever. Just because a tiny portion of the charts overlap it doesn't mean they are the same. For example in the second half of 2021 bitcoin went up 150%, can you honestly say that it resembles NASDAQ 100 that was struggling to go up 10%?!!!
and we know how the price fluctuate so sharply, where immediate gains/loss takes place in no time.
Not always though. The sharp moves happen only during bubble pops whether it's a drop after a bubble or a rise after a reverse bubble. Other times it is a more reasonable move.
Are we going to really align them to be on same level, or the price of Bitcoin is more stable than the Nasdaq 100 stock.
I already gave you an example, in comparison with bitcoin NASDAQ 100 is dead because it doesn't make that much move
“When we’re in an environment where all of those riskier assets are selling off, crypto is going to find itself doing the same,”
DO NOT confuse "crypto" with "bitcoin". Crypto, aka altcoins, are super risky but bitcoin is nowhere near as risky as them.
