At the moment PSB is ridiculously cheap, so now is a great moment to buy more. It doesn't matter how much you buy and hold, it helps. I, myself have been gathering more and more, , and i'm goin to hold until 5000 sats at least. Remember that there isn't too many of these coins circulating, and it doesn't take many big bagholders to get the price up, just don't sell guys.
Its a deadcoin. Nothing is innovating from this, any coin can do this remittance thingy cos all you need is a proper gateway. Besides all you can do now is to hold cos no one is going to buy.
