we must increase the number of our coins in the wallet.
Not really. It's obviously something people won't say no to, but most people here are looking for ways to increase the number of their coins by investing, trading, gambling, etc, and that is exactly where they go wrong. It's pointless to force yourself to increase the number of coins that you have if you don't want to buy them, or have a decent level of market understanding that you can put to work with trading for example.
