What is Halving?? Ive been in cryptpo world for just a month and know nothing about in technicalities in btc world.

For me who only have 100k SATs in my wallet. What should i do in this coming Halving? Should I hold my SATs or Sell it before Halving?? Or Sell It after Halving?

Do guide me the best way to utilize my small amount of SAT.

Thanks.
