A growth in the market cap is exactly what we need to see, as a higher market cap means that new money is being pumped into the market rather than more BTC being unlocked.

This is the type of stimulus which will help it reach the highs everyone is excited about.

You are right that the continuous movement of bitcoin is being built on the basis of bullish fundamentals. Willy Woo said Bitcoin's market capitalization would reach $ 1 trillion with around $ 25 billion in capital or funds. If this amount can be penetrated by Bitcoin, he also predicts that the value of Bitcoin will reach $ 54,000 per BTC or the equivalent of 709 million. I hope this is accomplished.

In as much the market cap keep increasing the volume also should do likewise for us to see some good movement; when the whales start their sell-off or profit taking from month end. Basically the volume should be that which determine what happen to the current market than the market cap, becasue we will see such because of the coins in circulation that has increase from 2017 till date. Hope to see the market bullish throughout the year and to year 2021.

Wow, this is really some good info and everybody should keep this in mind while looking at the marketcap. Thanks for letting us know this 

But also this made me curious whether the market cap has increased or actually decreased so I did a little research.
I found that the marketcap on 18th of last month was around $211 billion and as of yesterday the marketcap was around $332 billion.
Doesn't this mean that more money is pumped into bitcoin ?
Well I guess it might also be because of the rise in bitcoin's price, since the chart is showing the value in USD 

The below chart depicts the rise in marketcap for bitcoin.


 

Au contraire. Current ATH mcap we see is exactly because more BTC has been unlocked/mined in the last few years, since BTC didn't reach ATH yet. Personally, I don't think that mcap is very important metric as it can be very misleading. It's nice to look at, but nothing else really.

First of all, it's often used by various shitcoins to attract new investors who decide whether to buy or not something depending on the mcap rank. For example, you can make some shitcoin with huge supply, get it on some irrelevant exchange, pump the price and get unrealistically high mcap.

2nd, as we all know mcap is calculated by multiplying current price and current amount of coins in circulation, but then again we often have no idea what's the circulation. In BTC case, 18,547,962 has been mined up until now, but are all of those coins in circulation? What about all lost BTC, should that be counted too?

In the end, if mcap increases  or decreases by xyz billion, it doesn't mean that amount of money entered or exited that specific market.

Due to the adoption of PayPal and some billionaires and MCAP of bitcoin has been touching its ATH.

There will be more fund management company come to use bitcoin as portfolios. It's the only thing that bitcoin needs to break its old ath. Bitcoin has more supply compared with a  few years ago and we will be facing another all-time high for bitcoin mcap when the new ATH will be achieved.

This is the reason why Market Cap hits its ATH.

The total supply of it now is higher compare to what it was in 2017 causing its Market Cap to go higher. This just shows that there are more money coming in into Bitcoin though I don't if most of these are smart money (coming from institutions) or dumb money (coming from investors who got hyped by the recent rise of Bitcoin). Either way, it is beneficial for the holders .

I can not disagree with you but people must realize that there are lost bitcoin and the marketcap they see on coinmarketcap or coingecko or media is not real marketcap. If they know it they will have more in-depth view on marketcap.
