We can not deny that bitcoin is still the best coin in the market and there are still many investors who would like to prefer for bitcoin ,despite the falldown of market price value ,but still they will invest in bitcoin ,so this will be the reasons bitcoin volume is still rising.
I think because the supply of Bitcoin is at a fixed level, I don't think that increasing supply is a way to increase market capitalization, even though not all 21,000,000 BTCs are being traded on the market, what really drives the market. cap with the price and not the supply. So to answer your question, it will still rise in terms of price and market cap, see where the price is and the volume is still increasing.
You are still asking the same question as "Do you think Bitcoin will rise in price?" as the only way to increase market capitalization, of course, the value of Bitcoin is also increasing.
