Not enough ways to get blobcoins

[y21]

Is your feature request related to a problem? Please describe.
The only way to gain blobcoins is by requesting the daily reward, which only gives 20 blobcoins.

Describe the solution you'd like
There should be more ways to get blobcoins:

• Nomming others (reward depends on whether the opponents' tier is lower/higher)
• Hiding behind Y walls for X seconds (small reward, 5 for every 20 times?)
• Move Z pixels (for every 10K = 75?)

Describe alternatives you've considered

• Reward less/more blobcoins for the daily bonus.
