I am using coinwallet.co services since two years ago without issues, but if Faircoin is not having issues because the people have not the wallet opened staking, i think it would be useless.
Sorry. I'm not sure if I got what you mean?
You mean it is better for network if many people have there own wallet open for staking instead of staking in an onlinewallet with POS-Pool?
maybe, but I think the average user will leave his wallet open only once in a while.
they could possibly increase their POS rewards with that Pool.
otherwise I doubt this will be the case for people that stake with their own wallet very often.
We are going to leave POS after faircoin 2 deployment, which should be in june. So, that not should be an issue at that moment
