There is limited amount of money in the crypto currency. So for every new coin, it will dilute the funds into bitcoin.

Most of the new coins are scams or of little usage. They will die and the money will flow back to bitcoin again.

The Ethereum is in some trouble at the moment. I hope it will recover from the recent crisis. It is quite unique coin.

Many people mine the Ethereum and sell it for the bitcoin. If its price drops too much, they will get less bitcoin.

At the moment, the volume of the Ethereum and its Class version is very large. It seems people are selling bitcoin to get those.

The volume of the ETC and ETH has reduced in the last few days. The combined volume is just 40,000 now.
