I believe that there is no direct connection between the volume of trades on crypto exchanges and people's interest in cryptocurrencies, because many holders of cryptocurrencies do not trade them, keep their coins in their wallets or on the stock exchange in anticipation of price increases. Some people want to buy Bitcoin or altcoins at a lower price, so they are holding USDT and other stablecoins now, so they also do not create trading volumes on the exchange, but they have an interest in cryptocurrencies.
