One of my favourite altcoins is GALA.
Why?
Well, they have halving in the tokenomics, something like BTC invented so it gives less inflation in the eco system.
They have millions to promote.
They want to be Steam on blockchain.
They are in the gaming industry, one of the biggest industries in the world.
They have actual products that are working.
Their token is cheap at the moment.
They have big community of 2 millions people or maybe more.
