They want me to proof that real owner of the address:
M8vkrEVPJCDn54L3TN64W3Grrq3KkBNVXh
is Dodopool mining pool
And that all transaction from this address withdrawed from this address to my address on HitBTC - MJC9NV82j6upskkUjqNsRxvgCEJwuLvU5F
How can I possibly prove that

M8vkrEVPJCDn54L3TN64W3Grrq3KkBNVXh
is one of the 3 addresses used by mining for dodopool, the other two are
MAXwUSQKHWxVYvpg4Cs3epPQTLKg14WjaB and
MX2evLyh7pcW4SevTzs1CbyQCf9C8fPmWi
these addresses are recognized by explorer as dodopool blocks, try to ping one of the admins on telegram or discord, they can send an email from "mvs.org" domain confirming "yes these addresses belong to dodopool" sven and kesalin are generally really helpful with these.
