13.04. I participated in your ICO, 0x522b6721717287fa2237f64c458f941311aa7c9a60948511f2807b510f6f4280, but today I found that ETH is lying motionless. I wanted to translate the ETH back, but could not find the private key. You can restore the private key from the wallet 0xb30d9ed26edb1fac1cf2606b698a828ede90021e ? I have access to the wallet 0x273f365db20605e38e0250da05b51f339a7da839, from which the transaction was made and I can prove that the transaction was made by me.
