This is an important point, many refuse to enter into investments in this period, but starting a project with the market down there has its advantages, higher growth during bullfights is one of them
Since fiat is dominant, services tends to adjust prices based on much a token/coin is worth, I mean, if service A costs 1 ETH when it's priced at $400, if ETH go to $800, they usually cut the price in half and you're going to pay 0.5 ETH for the same service. You can also see it in ICOs, back when ETH was worth $200 hard caps were very high ETH wise
Are there any goods/services that have FIXED price in crypto? I haven't met such, but probably they exist.
