If the community does not like the proposal by the Vitalik and other developers, they do not have to adopt his proposal.

That is right. That is why the ETC still exists. However, if it does not have many supporters, it is just a pump and dump tool.

I noticed the ETC price has dropped more than 70% from the peak. That is even before the dump by big holders.

The ETC price has risen a bit in the last few days. But the price is still lower than the price a week ago.

In the past week, the price of ETC is more stable than the ETH. It seems it has some people to stablelise the price.

Both coins are trading within a small trading rate. They might be consoidating at the moment. before the next move.
