One company I would suggest checking is ExServers. I found their https://exservers.net website while comparing cryptocurrency friendly hosting services. They accept Bitcoin, Litecoin, Ethereum, and Monero, so customers are not restricted to a single digital currency. I also noticed that they emphasize customer privacy and offer offshore server locations. Their no contract approach is another useful feature, particularly if you are testing a new project and do not want to commit to a provider for an extended period. They also publish information about their abuse prevention policies, which is important when choosing infrastructure for business use. I would explore their available services and compare the technical specifications before making a purchase.
