SkySilk is a newly established VPS hosting merchant in the United States (the specific establishment time is uncertain, and the merchant’s promotional materials can be traced back to May 2018). When SkySilk was first established, it seemed that it started to pursue the path of low-priced VPS hosting, priced at US$1/ Monthly VPS hosting, and after binding a credit card, you can get a free VPS hosting for one year. However, now you don’t need a credit card. You only need to bind a Paypal account (no payment required) to get a VPS host for free. Each account that registers for SkySilk can get a $10 coupon. If you purchase a VPS host for $1, you can It’s almost 10 months of free use, which is equivalent to getting a free VPS. I briefly tested the free VPS host provided by SkySilk: 512MB memory, 10GB SSD hard drive, and 500GB monthly traffic. In terms of speed and performance, it is still worth $1. Of course, it is worth using it for free for 10 months. As far as I know, VPS currently selling for $1/month include Virmach low-price VPS and AnyNode VPS.

Only when the invitee spends $50 in SkyPoints within one year can he get 2500.Seeing such a rule, I finally realized how shrewd the merchants are. I am afraid that few people will spend $50 on a VPS of $1/month within a year. Therefore, some students came up with the idea of "swiping orders" again. It is recommended here not to abuse it.
