Hi! what's this link for?
And, what's the update on the dividends?
It's an online wallet that stakes. 24 hour staking. I have some coins there.
Is it safe? And, will it stake more coins than if you keep your coin on your computer?
Well. It's as safe as any 3rd party... So, no. Realistically your coins are only safe if you hold the keys to the wallet they are in.
I find I stake more on my PC but I am holding a higher balance on my PC. So, it's hard to be sure.
One benefit of staking on POSwallet is that you can stake 24/7 without having to have the wallet open on your PC. Which leaves your PC available for whatever else you might need it for. I work from my PC so it's convenient. I still prefer to stake on my PC though. Truthfully, I'd like to build another PC on my LAN and use that for staking only. It's also cool to have an air-gapped PC with cold storage.
