Dude  I don't know if you'll understand this but it wouldn't be nice categorizing such an outstanding digital asset with the so called cryptocurrency, bitcoin is too unique to be called cryptocurrency, I know you've had about the so called pump and dump shits that has littered the so-called crypto market which I believe you might have fallen victim to one of those shits, so would you rather see bitcoin as coin of it own or do you prefer associating it with those project that has no life span and nothing ot offer, I think you should understand something, the word crypto should be used when you want to talk about shits not bitcoin, the last time I check bitcoin has never fail to represent itself so I don't know the explanation or definition you need again to Validate the fact that bitcoin shouldn't be categorized as cryptocurrency.
