Bitcoin and Ethereum is overvalued now and it is impossible to earn big profits on investing on BTC and ETH.
On new projects it is possible to earn much more profit and money.
That is why many investors monitor the market to find new projects for investing.
The risk in new projects is also very big so investors should also consider this because they all don't hate Bitcoin and Ethereum because both coins are always very suitable for long-term investment not for short-term like in the new project.
So only small investors think Bitcoin and Ethereum are expensive, because they can't afford to buy in large quantities, while big investors always monitor Bitcoin and Ethereum for them to buy as much as they can.
