Or if you don't have that amount of XSG you can make use of a shared masternode service like evonodes for example.
But keeping the coins in your wallet wont get you anything because there is no such thing as POS implemented. Only POW/MN
You will benefit by the growth of Snowgem though. So keep those coins and wait for XSGs time to come. It will surely come!

That guy can use shared masternode service, and with very low cost from VPS service. In my opinion, Proof of Stake and Masternode coins help to protect our planet better by consuming less energy than proof-of-work coins. 10000 coins to have right to set up Snowgem masternode is a high collateral, in my perspective, so using shared masternode is better choice.
