Based on what I remember, the early Bitcoin was priced more like a hedge against corrections in the stock market.
Do you have any solid numbers like the correlation coefficient, which measures the strength of this relationship, and how it changed for the last few months? Basically, what is your methodology or is it just how you feel?
Since February Bitcoin and most altcoins have been trading in the sideways market mostly. This is normal for the stock market (on average), but that doesn't mean that the cryptomarket has turned into a variety of stock market. Bitcoin had been rising nonstop in the second half of 2017, but it wasn't always like that. There were enough periods in the past when Bitcoin behaved very much like the first tier stocks, for example, in the first half of 2015 when it had been trading between $200 and $300.
