i can't thank you enough for your fast help but i am sure putting my coins on a pool is huge risk not worth taking and i was thinking maybe i can purchase 2GB VPS and than put all my wallets there to run all the time and get interest
is it a good idea???
If you do use a VPS you have to make sure you setup good security on it, use all TOR and identity masking that you can and use multiple firewalls, super strong passwords, also never connect to it through any known computer just to be safe. You can never be too careful.
You wouldn't even need a 2BG ram VPS, you can just go with a small one unless you want to host multiple wallets. Proof of Stake is so efficient that even with a couple POS Coins, you could host full nodes pretty easily and you aren't spending mega bucks on power bills. If you wanted to get a bit deeper into it, you could schedule your wallets to connect for certain periods and close again with a task scheduler.
