Is there any update about this?
I registered on poswallet just to try their service. I didn't notice any problem but i keep whatching. It's a bit annoying that you have to create every single deposit address one by one.
What's your opinion about this service?
I have had problems in the past - missing deposits, shorted deposits, and recently found out that I have a $500 USD per day withdraw limit. I have started several support tickets, & all except 1 or 2 were answered in a timely manner.
It is a bit risky trusting a third party with your coins, but sometimes greater risk equals greater reward. I have always felt like coins should be kept in your possession at all times simply because one of the main benefits of Bitcoin/altcoins is that it takes away the need for third parties. Having said that, I'm not sure anyone ever imagined there would be this many digital currencies, several of which using a PoS algorithm. Even with a current top of the line computer, I don't think it would be possible to stake 102 different coins at the same time using only a PC & standard internet connection (which is currently what poswallet.com can do)!
In my honest opinion, I must say that they have done a great deal of growing over the past few months - not only in terms of a larger user-base with more coins, but its been quite obvious to me that a considerable amount of time/work has gone into developing! UI continues to improve, more PoS coins have been added, block explorers & an Exchange have been built (whether they work well or not is unknown to me simply because I haven't tried either of those features). However you look at it, time, money, & resources have most seemingly been spent recently, I get the feeling that their intentions are good..
