Looking for a offshore crypto vps provider with great network speeds in Europe. Needs to accept major coins. Have you guys used any host that offers great unmanaged plans?

Hi. If you need excellent network speeds in Europe and solid offshore privacy, I highly recommend this crypto hosting. Their Netherlands location is fantastic for unmanaged plans-you get full root access, great hardware, and zero bloated software. They accept major coins smoothly and keep things completely anonymous without annoying KYC. I've been running a node there for a few months, and the connection speeds are stellar.

Do they allow port 25 to be opened on those unmanaged Netherlands nodes, or is mail traffic completely blocked?

Port 25 is blocked by default to prevent spam, but you can easily request the support team to open it after your account clears a brief check.
