IVPN vs VPN.ac

They are kept for troubleshooting reasons.

Bitcoin, cash and PayPal are accepted.

You can switch between a single VPN connection (singlehop), or routing your internet traffic through multiple VPN servers (multihop) at any time. The latter increases anonymity, but comes at the cost of a slightly worse performance. Furthermore their multihop system has a built in restriction that dictates that it must be a hop from one country to the next, so no Dallas to LA hop, but because of this there should be nothing too shocking about the overall latency. NY - Toronto - London can still edge under 100ms, LA - SLC - HK hitting 350 - 380ms is pretty normal for everyone. A single hop from Brooklyn to Jersey can be as low as 7ms, with 20ms to Atlanta.

To further the point, really this means that if you route through a US node they may throttle you, but it may help to be on a private tracker. It certainly wouldn't affect you if you're connecting from a peer through Canada or Bucharest.

Except for BitTorrent in US, you can use any and all protocols at your disposal, no traffic is restricted.

VPN.ac has fast throughput rates.
