There is also more liquidity. So one large whale won’t be able to manipulate the market as before. There is going to be less volatility so no more days where bitcoin has 20% swings in price.
Naturally, as all markets, bigger market cap, less volatility. Some times there will still be 20% or 30% volatility but it will occur with lower intensity. Gold, oil, and stocks can have high volatile days but such days won't appear too often. Same for Bitcoin price volatility in future as if some day Bitcoin price is $1M, we can not expect 10% change in a day, it will be $100,000 that is too much.Quote
Negative is that there is more regulation. Which can be seen on how exchanges are strict with their users.
We can not have both like bigger adoption, bigger market cap but the same or less regulations on this market. We actually want to see this market to grow bigger, Bitcoin to gain higher value and higher price, so we must accept more regulations like how governments do on other markets.
