When the price of Bitcoin and Ethereum falls, this is not the best time for new projects, because BTC and ETH received by projects also decrease in price and reduce the amount of money raised by the project.
However, everything here primarily depends on the quality of your project, if it has development prospects, then there will be many investors.
for some reason it seems to me that recently new projects have been incorrectly advertised and therefore investors are not very willing to invest their funds. First of all, you need to show the benefits of the project in society and how quickly it will be implemented in the daily life of a person.
