Aren't you calculating bandwidth for a singly-connected node? A "highly
connected" miner could have 30-100 node connections so you probably need
to increase your traffic estimates by that factor.
I.e. For 100MB blocks, 30-100 Mbps and $60-$100 per day data costs.
> You should be able to handle 20MB blocks no problem; if I round up to
> 100MB per block that works out to 1.3Mbps.

> We also use Aliyun and Linode cloud services for block

> per GB for

> That speed will handle 20MB blocks no problem.
