great new service that allow webwallets that are able to stake for POS able coins

for now its just a webwallet that can stake

but later on it will be linked with android apps and marketplaces too

i think now when this company is in the startup phase its maybe possible even a small coin can get added

later on it will be very difficult for small coins get a slot i guess
