币界网报道：The overall crypto market showed a downward trend in May, but the open interest of Ethereum futures hit a record high due to the approval of spot ETFs. This month, the transaction volume of Bitcoin and Ethereum on the chain, the transaction volume of stablecoins on the chain, and the income of Bitcoin miners all declined, while the Ethereum staking income, Ethereum destruction, and Ethereum options trading volume all increased. The market share of cryptocurrency exchanges in the spot market, futures and options markets have all changed to varying degrees.
