Big players can join hands and do whatever they want.
I can start a fork and increase the supply of coins, but if nobody follows my fork there is no future for it.
Same for the "big players", if people don't follow their chain, there will be no coin.
Oh, and please sell!!! "Investors" like you are the last thing BTC needs.
And also coins have risk like every other investment there is nothing known as guaranteed profit
BTCLovingDude has already explained once, I really don't understand how you can be so dense!!!
Anything can be changed, limit, block time, block size but you need consensus for that.
The ones that missed the train are having this idea.
Basically they want to dilute the already mined bitcoins, rendering the so called whales with less coins/supply.
It's not like they will make more money with this, but the newbies will have a more of a say in trading.
One example will be this...from 21 to 210 million.
Of course the impact in price will be instant, (in reality it will turn to zero but for the sake of the argument let's overlook this ) and the value will drop by 10.
In the end if bitcoin will be successful, the entire market cap of all coins will be the same, just one bitcoin will be worth /10 of the original. Nothing to gain here, nothing in ROI.
But the whales and early investors will no longer hold half of the coins, they will have only 5% of them.
This is why some advocate this increase in supply.
But in reality it will turn bitcoin into fiat, one hundred nails in the coffin.
