Ways to earn Razer Silver decreasing

As we know Razer Silver is the currency of the reward system from Razer. There are lots of ways to earn it. BUT these days it's getting really hard to get those.

Here are some ways we can earn it

• Spending Razer Gold
  
• Razer Cortex PC
  
• Razer Cortex Games (Mobile)
  
• Skibre
  
• Razer Insider
  
• Razer Cortex Squad (Event)
  
• GAMMA mining
  

Recently there is one way we can earn which is by playing tournaments at Mogul.gg but now it seems like mogul no longer provides tournaments for us to play not sure why.
Razer Silver from Razer Cortex (Mobile) also decreasing. There is sometime we can earn 200 Razer Silver per game and DOUBLE silver for the other game during week ends. Now i only receive 2 games which provides 25 silver per game. No more 200 Silver and double Silver
Cortex Squad (Event) we can earn alot from it but the system delay causes the event to be quite unfair so we cant win anything or only a little from it.

Is there anyone who have any idea how can i earn more silver?
