Task Scheduling Not Working Properly - Laravel

I am new to laravel. I just made a command which adds 10 points for each user. It is running successfully when executed but when I use it with the task scheduler it doesn't work. Here is my command :

public function handle()
{
    $x = User::all();
    foreach ($x as $c){
        $u['points'] = $c->points + 10;
        User::where('id' , $c->id)->update($u);
    }
    echo 'Daily Bonus Given';
}

Here is my Kernel file :

    protected $commands = [
    Commands\daily_bonus::class,
];

/**
 * Define the application's command schedule.
 *
 * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
 * @return void
 */
protected function schedule(Schedule $schedule)
{
     $schedule->command('daily:bonus')
              ->everyMinute();
}

/**
 * Register the Closure based commands for the application.
 *
 * @return void
 */
protected function commands()
{
    require base_path('routes/console.php');
}

When I run php artisan schedule:run, it executes the command only the first time and not after a regular interval. Thanks
